Summary
Human activities introduce emerging pollutants like microplastics and pharmaceuticals into aquatic environments, posing risks to ecosystems and public health. Further research is needed on their combined effects in coastal zones.
Area of Science:
- Environmental Science
- Ecotoxicology
- Marine Biology
Background:
- Human activities and climate change increase land-sourced pollutants in aquatic systems.
- Emerging contaminants like microplastics, pharmaceuticals, and personal care products raise global health concerns.
- These pollutants include microplastics, persistent organic pollutants, antibiotics, and endocrine-disrupting chemicals.
Approach:
- Reviewed sources, distribution, and transport of key emerging pollutants in estuarine-coastal environments.
- Analyzed factors influencing the environmental behavior of these contaminants.
- Examined adverse ecological effects and human health risks associated with emerging contaminants.
Key Points:
- Microplastics, PFAS, antibiotics, and EDCs are prevalent emerging pollutants.
- Estuarine-coastal environments are key pathways for pollutant distribution and transport.
- These contaminants pose significant risks to marine ecosystems and human health.
Conclusions:
- Understanding pollutant interactions is crucial for marine pollution control.
- Future research should focus on the combined environmental behavior and health risks of multiple emerging pollutants.
- This knowledge supports marine pollution prevention and the sustainable marine economy.

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

01:27Effects of Chemicals: Overview
1.3K
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

19.7K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

01:26Toxic Reactions: Overview
1.1K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:27The Periodic Table and Organismal Elements
18.6K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
