This document discusses emerging pollutants in India. It defines emerging pollutants as chemicals and compounds recently identified as dangerous to the environment and human health. Some classes of emerging pollutants discussed include pharmaceuticals, personal care products, pesticides, and microplastics. The document outlines effects on human health and marine species. It also discusses the presence of various emerging pollutants in Indian waters and treatments technologies like biological treatment and advanced oxidation processes.

1. EMMERGING POLLUTANT
• Name: RICHARD D. MALUSU
• Corse : ENVIRONMENTAL SCIENCES -AN
INTERDISCIPLINARY APPROACH
• Enrolment No. 220502001

2. EMERGING POLLUTANT
• Pollution is the any that can be increase in the
concentration of matter that are generated by the human
activities that will degrade the environment
• Three types of pollution
• Air Pollution
• Water pollution
• Soil Pollution
• Any substance that cause the pollution is the Pollutant.

3. Dfn….
• The emerging pollutant are entering in the environment
everyday due to the human activities (anthropogenic)
• Emerging Pollutant is the chemical and compound that
have recently been identified as the dangerous to the
environment and consequently to the human health.
• Emerging pollutant can be found in the ground water,
surface water, municipal waste water, drinking water and
food sources

4. • This emerging pollutant are not monitored or regulated in
the environment with potentially known as adverse
ecological and human health effects.

5. CLASS OF COMPOUND IDENTIFIED AS
EMERGING POLLUTANT
• These pollutant it include the following compound
• pharmaceutical
• Plant hormones
• Ant-biotic
• Personal care product
• Pesticides
• Steroids
• micro plastic

7. EFFECTS
• Human Health
• Loss of species in marine system

8. EMERGING CONTAMINANTS IN
INDIAN WATERS
• Pharmaceuticals
• 78 percent of the sewage generated in India remains
untreated and is discharged in rivers, groundwater or lakes
.This could explain the reason for high levels of API in water
matrices
• investigated the presence of pharmaceuticals in Ahar River in
Udaipur city and found 19 pharmaceuticals including 4
antibiotics. The river originates as a potable water source
which gets contaminated as it moves through urban areas. It
was observed that the concentration of emerging
contaminants increased as it passed through densely
populated regions indicating the potential discharge of
domestic wastewater into the river.

9. PERSONAL CARE PRODUCTS
• Triclosan and Triclocarban are the commonly used antibacterials in
soaps, shampoos, hand sanitizers, etc. The occurrence of triclosan,
triclocarban and parabens (preservative in cosmetics), commonly
used in personal care products (PCP), in water samples from the
Kaveri, Vellar, Tamiraparani rivers and the Pichavaram mangrove in
South India
• DEET used in mosquito repellents has been detected in Ahar River,
Udaipur (William et al. 2019). This indicates the contamination of
river water by domestic wastewater. It was found that the
concentration of PCP increased with an increase in population
density. The presence of benzotriazole ultraviolet stabilizers
(BUVSs) which are used extensively in personal care products such
as soaps, shampoos, sunscreen lotions, shaving creams

10. ENDOCRINE DISRUPTING CHEMICALS
• Endocrine Disrupting Chemicals (EDCs) have received wide
attention recently due to its ability to disrupt the endocrine
system of humans, special vulnerable groups include
pregnant mothers, children and elderly. The occurrence of
phthalates, polychlorinated biphenyls (PCBs), plasticizers and
perchlorate have been reported in several studies.
• PCBs have been reported to affect the reproductive system.
Chakraborty et al. (2016) determined the total PCBs in River
Hooghly and River Brahmaputra at concentrations of 0.233
μg/L and 0.161 μg/L respectively. PCBs can make their way
into the environment through leaching from open dumpsites,
poorly managed landfills and improperly discarded electronic
waste

11. PERFLUORINATED COMPOUNDS
• Recent studies have reported the presence of perfluorinated
compounds (PFCs) in groundwater, surface water, drinking
water, snow and precipitation water. Of the PFCs reported,
short-chain
• The highest concentration reported in the groundwater and
River Ganga were 0.033 µg/L and 0.025 µg/L respectively
• It indicates the contamination of ECs in water through the
recharge pathway and its mobility through the substrata. the
occurrence of PFCs in surface water bodies in several cities
in India including the stretch of River Ganga. High
concentrations of PFCs were reported in Chennai followed by
Allahabad, Varanasi, Patna and Kanpur.

12. PESTICIDES
• The determination the concentration of pesticides such
as Chlorpyrifos, phenoxy acetic acid, diuron and atrazine
in Ganga river, groundwater samples in shallow and
deep abstraction wells from Varanasi and Ramnagar,
Uttar Pradesh (UP). The high concentration of phenoxy
acetic acid was observed. Analysed the presence of
organochlorine pesticides (OCPs) such as HCH, DDT,
endosulfan, heptachlor and aldrin in river Hooghly (RH)
and river Brahmaputra (RB).

13. ARTIFICIAL SWEETENERS
• The established the presence of Artificial Sweeteners
(ASWs) in Indian water matrices. ASWs such as
sucralose are widely used in India in food and
beverages. The sucralose concentration in river Ganga
was reported as 0.05 µg/L. Besides, the groundwater in
Varanasi and Ramnagar were also found to be
contaminated with sucralose even at a depth greater
than 140 meters (Lapworth et al. 2018).

14. TREATMENT TECHNOLOGIES
• Improvement in lifestyle, urbanisation, agricultural and
industrial practises has resulted in an increase in the
load of ECs into the water environment. The control of
ECs is possible through the incorporation of efficient and
cost-effective treatment technologies for the removal of
ECs. The method are
• employing adsorption,
• biological treatment and
• advanced oxidation processes (AOPs)

15. BIOLOGICAL TREATMENT
• Biological treatment using constructed wetlands and
activated sludge processes have been evaluated by
several studies. the removal of surfactants and personal
care products such as sodium dodecyl sulphate (SDS),
propylene glycol (PG) and trimethylamine (TMA) from
greywater using a hybrid constructed wetland (HYCW).

16. ADVANCE OXIDATION PROCESS
• AOPs are a promising technique in the degradation of
ECs such as pesticides and API.
• ADSOPTION
• Adsorption of ECs onto the adsorbents is a way to
separate the ECs from the water matrix while it presents
no significant treatment and reusability of adsorbents is a
challenge. Several studies have investigated the various
adsorbents for the adsorption of ECs. The commonly
employed adsorbent is activated carbon.

17. CONCLUSION
• The occurrence of emerging pollutant in the environment
continue to generate the increasingly problem. So the
increase of water monitoring and development of new
technology for treatment of mixture of merging chemicals
are detected in environment.
• The past studies have established the presence of ECs
such as API, PCP, ASW, pesticides and EDC across the
Indian water environment. It was observed that certain
ECs are predominant and ubiquitous
