Here are a few possible reasons why the government has not banned BPA more quickly:
1. Chemical companies that produce and use BPA in plastics manufacturing exert significant lobbying influence. Banning chemicals could hurt their profits.
2. The effects of low-dose exposure to endocrine disrupting chemicals like BPA are complex and long-term. It's difficult to definitively prove health impacts, which gives chemical companies arguments against regulation.
3. Government agencies tend to be more conservative in banning chemicals already in wide use. They prefer to see overwhelming scientific consensus first before taking drastic regulatory action.
4. Alternatives to BPA must be developed, tested and brought to market. Transitioning entire industries to new

Types of hazards Prepared by Ms.Ludangco
A hazard is a situation that poses a level of threat to life, health, property, or environment. Most hazards are dormant or potential, with only a theoretical risk of harm. However, once a hazard becomes "active", it can create an emergency situation. A hazard does not exist when it is not happening. A hazardous situation that has come to pass is called an incident. Hazard and vulnerability interact together to create risk.
5203 Disaster and Climate Resilience, Occupational Health and Safety
This document discusses occupational health and safety topics including occupational health, occupational hazards, and common workplace hazards. It defines occupational health as promoting worker well-being and preventing work-related illness and injury. Workplace hazards can be biological, chemical, physical, safety-related, or ergonomic in nature. Biological hazards may include bacteria, viruses, or dusts that can cause respiratory illness. Chemical hazards include cleaning products, hair dyes, and other substances that can cause skin or respiratory issues if not handled properly. Identifying hazards is important for assessing and reducing risks to worker health and safety.
Topic 2
This document discusses factors related to human health and illness. It notes that health is defined by the WHO as complete physical, mental and social well-being, not just the absence of illness. Illness occurs when an organism's function is altered, showing symptoms. To maintain good health and avoid illness, one can control their environment, habits, personal characteristics, and access to preventive healthcare. The document also categorizes illnesses based on causes, symptoms, frequency and transmission; and discusses how the body defends against infection through external barriers and the immune system.
Environmental & Occupational Diseases
Environmental and occupational disorders are an important aspect of clinical medicine. Physicians, employers, employees, and the general public need to be aware of epidemiological and clinical findings of these disorders and how to treat and prevent them. Environmental pulmonary diseases result from inhalation of various pollutants and the lungs are continually exposed. Pathologic processes can involve the airways, interstitium, and pleurae. Guidelines for diagnosing an occupational lung disorder include exposure to a known hazardous agent, appropriate latency between exposure and symptoms, symptoms consistent with the exposure-related disorder, and no other more likely explanation for signs and symptoms. Prevention focuses on reducing exposure through administrative controls, engineering controls, product substitution, and respiratory protection.

Occupatinal health hazards
Occupational health refers to potential risks to worker health and safety from their jobs outside the home. It aims to promote worker well-being, prevent job-related illness, protect workers from health risks, and ensure a balance between workers and their occupational environments. Occupational health hazards include physical, chemical, biological, and psychosocial risks that can cause diseases, injuries, stress, and disorders if not properly controlled. Preventing occupational diseases involves measures related to the work environment, medical care, health education, and protecting workers from various hazards.
Occupational diseases 11
Occupational diseases are diseases that are caused or aggravated by the work or work environment. Some key points:
- Occupational diseases can have varying time frames between exposure and symptoms, from immediate to decades later.
- Major causes of occupational diseases include physical, chemical, biological, and psychosocial hazards. Common examples are respiratory diseases from dusts or fumes, musculoskeletal disorders, and work-related stress.
- Prevention of occupational diseases involves controlling exposures through substitution of hazardous materials, engineering controls, administrative controls, personal protective equipment, and health monitoring programs. The goal is primary, secondary, and tertiary prevention.
Ipm agrostudies
The document discusses integrated pest management (IPM), an approach developed in the 1970s as an alternative to the "annihilation" concept of using pesticides. IPM uses a combination of cultivation practices, biological and mechanical controls, and targeted pesticides when needed to keep pests below economically damaging levels. It aims to minimize risks to humans, crops, and the environment by considering economic, ecological and social consequences. The key principles of IPM include monitoring pest levels, determining economic injury thresholds, and making informed decisions about the most appropriate control methods for each situation.

The main difference between hazard and disaster is that hazard is a dangerous situation or event that poses a threat to humans while disaster is an event that actually harms human’s life, property and thus disrupts social activities.
Therefore, a hazard can lead to a disaster that will completely disrupt the life conditions of the victims. However, both hazard and disaster bear potential threat to humans since both can result in loss and damage to life and property. A disaster is more critical in nature than a hazard, which might turn into a disaster in extreme circumstances.
What is a Hazard?
Hazard is a general occurrence that is risky or dangerous to the affected people. Therefore, they are naturally occurring situations in the world, which cannot be avoided. Furthermore, they pose a threat to our lives.
There are two types of hazards as geophysical and biological. Some geophysical hazards are earthquakes, volcanic eruptions, droughts, floods, and some biological hazards are disease, infection, etc.
Based on their severity and the place of occurrence, hazards can be classified as disasters or not. Hazards have the potential to disrupt the living conditions of the humans; however, necessary precautions to avoid dangerous results can be taken before the hazard aggravates into a disaster.
Therefore, it can be assumed that hazard can also be a precursor to a disaster. Therefore, we can avoid the worse outcomes of a disaster that might follow a hazard if we take good disaster management steps.
What is a Disaster
A disaster has more negative consequences, unlike a hazard. Disaster is a degree of a hazard that has become more threatening. Therefore, a disaster can be defined as an occurrence that completely disrupts the normal life pattern of victims. In brief, a disaster is more catastrophic in nature. Furthermore, unlike a hazard, a disaster is more sudden and thus severe.
Disasters can also be categorized as natural disasters such as tsunami, tornadoes, volcanic eruption, etc., and man-made disasters like the consequence of technological hazards (for example, fires, transport accidents, industrial accidents, oil spills and nuclear explosions/radiation etc.)
However, an occurrence like a tornado in an uninhabited area will be termed as a hazard, and not as a disaster since though it still has destructive properties. This is because even though the severity of the tornado is still there, it did not cause any damage or loss to human life and property as it occurred on an inhabited area.
Biosafety Principles in the life sciences field
The document discusses six main categories of workplace hazards: biological, chemical, ergonomic, physical, psychological, and safety hazards. It provides examples of hazards that fall under each category, such as bacteria and viruses for biological hazards; liquids, vapors, and gases for chemical hazards; improperly adjusted workstations and repetitive movements for ergonomic hazards; radiation and temperature extremes for physical hazards; shift work and workload for psychological hazards; and tripping hazards, unguarded machinery, and electrical hazards for safety hazards. The document aims to help identify and control hazards in the workplace to prevent accidents, injuries, property damage, and downtime.
Powerpoint presentation about hazard and risk
This document defines hazards and risks, outlines common workplace hazards like physical, biological, chemical, ergonomic and psychological hazards, and discusses the importance of occupational health and safety. Hazards are things that have the potential to cause harm, while risk is the chance of being harmed. The effects of hazards can include injuries, illnesses, infections and diseases. The goal of occupational health and safety is to provide a safe working environment and protect workers' health.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
