Summary
Pharmaceuticals in the environment (PhMs) contaminate soils via wastewater and manure. Understanding PhM fate in soil is crucial for environmental risk assessment and remediation strategies.
Area of Science:
- Environmental Chemistry
- Soil Science
- Ecotoxicology
Background:
- Pharmaceuticals (PhMs) are emerging contaminants found widely in soils.
- Wastewater treatment plants (WWTPs) and animal manure contribute to PhM soil pollution.
- Conventional treatment methods fail to remove PhMs effectively from water and biosolids.
Purpose of the Study:
- To highlight the critical need for studying the fate of PhMs in soils.
- To inform risk evaluations for wastewater reuse and biosolid application.
- To emphasize the importance of soil remediation for environmental protection.
Main Methods:
- Investigating PhM adsorption/desorption to soil colloids.
- Analyzing biotic (biodegradation) and abiotic degradation processes.
- Assessing PhM transfer and plant uptake mechanisms.
Main Results:
- PhM sorption to soil is a key factor in plant uptake.
- Environmental and compound properties influence PhM behavior.
- Microbial activity and community size are affected by PhM exposure.
Conclusions:
- Accurate study of PhM fate in soils is essential for risk assessment.
- Understanding PhM behavior informs effective soil remediation strategies.
- Protecting soil health requires addressing pharmaceutical pollution.

01:27Effects of Chemicals: Overview
1.2K
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...

01:19Pharmacovigilance
778
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

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.

01:21Drug Distribution: Tissue Binding
2.6K
Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.

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.

01:10Drug Excretion: Miscellaneous Routes
48
Drug excretion involves various organs, including the liver, intestines, skin, and eyes. In the case of drugs or toxins, they can be actively secreted into bile by transporters in the hepatocyte's canalicular membrane. These substances enter the GI tract during digestion and may be reabsorbed into the body from the intestine. This process, known as enterohepatic recycling, can significantly prolong the presence and effects of a substance in the body. To interrupt this cycle, specific...
