Summary
Plasticizers like DEHP contaminate environments, posing ecological and health risks. Effective detection, treatment, and regulation are crucial for mitigation.
Area of Science:
- Environmental Science
- Toxicology
- Polymer Chemistry
Background:
- Plasticizers are vital for plastic flexibility but raise environmental and health concerns.
- Phthalates, especially DEHP, are persistent pollutants found widely in ecosystems.
- Plastic degradation releases these additives, leading to widespread contamination.
Purpose of the Study:
- To comprehensively review plasticizer types, properties, production, and environmental risks.
- To analyze existing research on plasticizer contamination in water, soil, and sediments.
- To evaluate current and emerging treatment technologies for plasticizer removal.
Main Methods:
- Literature review of studies on plasticizer environmental distribution and contamination (2022-2023).
- Analysis of plasticizer concentrations in aquatic and terrestrial environments.
- Evaluation of various treatment technologies for plasticizer remediation.
Main Results:
- Phthalates, particularly DEHP, are prevalent in aquatic and terrestrial environments due to plastic degradation.
- High plasticizer concentrations in industrial/urban areas exceed safe limits, risking ecological integrity and human health.
- Bioaccumulation in soil and water negatively impacts microbial communities and nutrient cycling.
Conclusions:
- Plasticizers pose significant risks to ecosystems and human health via bioaccumulation and potential food chain transfer.
- Current treatment technologies show promise but face challenges in cost and energy efficiency.
- Improved detection, cost-effective treatments, stricter regulations, and public awareness are essential for mitigation.

Types of Toxins
1.6K
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.

Bioremediation
18.2K
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.

The Phosphorus Cycle
36.5K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Types of Step-Growth Polymers: Polyesters
2.2K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Toxic Reactions: Overview
954
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,...
