This document discusses marine pollution and its causes. It defines marine pollution as the introduction of substances into the marine environment by human activities that result in adverse effects. There are five main types of marine pollution: direct discharge of waste, runoff, ship pollution, atmospheric pollution, and deep sea mining. Major causes of pollution include the discharge of municipal, agricultural, and industrial waste into waterways and oceans as well as oil spills from shipping accidents and ballast water exchange. Pollution decreases oxygen levels in water and releases toxic substances that harm marine life and degrade coastal environments. Strategies to address pollution include improved waste treatment, contingency planning for oil spills, and best management practices for runoff.
Marine Pollution
Pollution is the introduction of harmful contaminants that are outside the norm for a given ecosystem.
“The introduction by man, directly, or indirectly, of substances or energy to the marine environment resulting in deleterious effects such as: hazards to human health, hindrance to marine activities, impairment of the quality of seawater for various uses and reduction of amenities.”-UN definition of marine pollution
Common man-made pollutants that reach the ocean include:
pesticides,
herbicides,
chemical fertilizers,
detergents,
oil,
sewage,
plastics,
and other solids.
This document discusses marine pollution and its causes and effects. It begins with an introduction noting that while oceans are vital, human activity has degraded marine habitats. It then defines marine pollution and discusses various pollutants like sewage, pesticides, plastics, metals, oil, thermal pollution and their harmful effects. These pollutants accumulate in marine life and enter the human food chain. The document concludes by emphasizing the importance of preventing and controlling marine pollution to protect ocean ecosystems and human health.
This document discusses various types of sea water pollution including chemicals, metals, radioactive substances, solid waste, oil, sewage, and agricultural runoff. Major pollutants released into the oceans include billions of tons of ballast water, trillions of gallons of sewage, millions of tons of oil and solid waste. Heavy metals like mercury, lead and copper released from human activities pose serious threats as they accumulate in the food chain. Pollution has severe negative effects on marine life and ecosystems as well as public health. Prevention of pollution through changes in human attitudes and behaviors is important since the impacts of pollution on the environment can be long-lasting and irreversible.
Water pollution occurs when pollutants are discharged directly or indirectly into water bodies from various sources such as factories, sewage treatment plants, agricultural and livestock farms, and urban settlements. Major causes of water pollution include improper disposal of sewage and industrial waste, oil spills, seepage from landfills, excess fertilizers and pesticides, and littering. Water pollution has wide-ranging negative impacts like endangering plant and animal species, causing eutrophication, contaminating food sources, and affecting human health. It also leads to significant economic losses for industries like fishing and tourism.

Over 50% of the world's original mangroves have been lost, mainly due to aquaculture, agriculture, and deforestation. Shrimp farming in particular has led to significant mangrove loss in Asia and Latin America. In Thailand, shrimp farming expanded rapidly from 1970-1990 and resulted in the loss of over half of the country's mangroves. The expansion was driven by increasing global demand for shrimp and government support. While shrimp farming provided economic benefits, it also caused environmental problems like soil salinization, biodiversity loss, and pollution from farm effluent. Climate change further threatens mangroves by increasing risks of sea level rise, storms, and carbon release from destroyed mangrove forests. S

The major types of pollutants are pathogens, inorganic materials, organic materials, suspended solids, and radioactive materials. Sources include sewage, agriculture, oil, erosion, and industrial/domestic waste. Effects are risks to human and animal health. Prevention methods center around proper waste disposal, reducing runoff, and recycling/reusing water.
Marine pollution is defined as the introduction of substances or energy into the marine environment by human activity that has harmful effects. There are many types of marine pollutants including oil, heavy metals, solid waste, sewage, and invasive species. Major sources of pollution are land-based activities, atmospheric deposition, and maritime transport. Pollution has wide-ranging negative impacts on ecosystem health, public health, water quality, and coastal economies. International agreements aim to prevent marine pollution and reduce its costly impacts.
The document discusses various ways that the hydrosphere, or water environment, is being polluted. It identifies pollution by oil and mineral oil from shipping accidents and waste dumping as a major issue, with over 10 million tons of oil entering oceans annually. Other significant sources of pollution include sewage, heavy metals, acid rain, plastic waste, and radioactive waste. Proper management of waste and prevention of accidents are needed to address this growing threat and protect water resources that all life depends on.
This document discusses marine pollution, its causes, effects, and policy responses. It begins by defining marine pollution as the introduction of toxic substances into ocean waters from human activities. The major causes are identified as land-based pollution from sewage, industrial chemicals, plastics, and oil spills. Effects include harm to marine animals and ecosystems, disruption of coral reefs, depletion of oxygen, and impacts on human health. International agreements like MARPOL and UNCLOS aim to control pollution and protect marine environments.
India has a long coastline and large exclusive economic zone with significant marine fisheries potential. Fisheries management responsibilities are shared between central and state governments. The central government ministries of agriculture, commerce, environment and defense play roles, while states have jurisdiction over territorial waters. Management measures include gear restrictions, closed seasons and areas. Overfishing from lack of controls threatens stocks, highlighting the need for sustainable fisheries management.

Proposals are made for better management, wastewater treatment, sustainable agriculture, and education to restore the sensitive ecosystem. EU funds are available to support protecting and restoring the area.
Sea of Change: Your Role in Marine ConservationPaula Bernasor
This document discusses marine conservation issues in the Philippines. It notes that the Philippines has over 36,000 km of coastline and is home to the Coral Triangle, which contains 75% of the world's coral species. However, the document outlines several threats facing Philippine oceans, including rising temperatures and acidification from carbon emissions, coral reef degradation, loss of sea grass and mangroves, overfishing, pollution, and rising sea levels. It emphasizes that overfishing may cause fish populations to decline by 90% in the next decade if not addressed, and that marine ecosystems provide food and livelihoods for millions of Filipinos. The document calls for greater protection of oceans as they play an important role in carbon storage
The document discusses World Wetland Day, which is celebrated annually on February 2nd. It provides background on the Ramsar Convention, which established protections for wetlands of international importance. Wetlands provide numerous benefits, including water purification, flood control, biodiversity, and carbon storage. However, many wetlands have been lost due to activities like agriculture, fishing, and pollution. The document advocates educating communities and taking steps to preserve remaining wetlands, such as by planting native species and avoiding development in wetland areas. It highlights some important wetlands in India and efforts to raise awareness and sustainably manage wetlands going forward.
Marine pollution refers to the introduction of harmful substances into oceans and water bodies, adversely impacting marine life and ecosystems. It can result from industrial discharges, oil spills, plastic waste, agricultural runoff, sewage, shipping activities, atmospheric deposition, and illegal dumping. Major types of marine pollution include plastic pollution, oil spills, industrial discharges, agricultural runoff, sewage, shipping activities, and atmospheric deposition. Preventative measures include stricter regulations, use of double hulled tankers, reducing single-use plastics, and enforcing waste disposal laws. Two case studies described oil spills in Chennai, India and the Gulf of Mexico.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
