A Review on Emerging Contaminants: Effects on Human Health and Cancer Risks
AI summary Read the abstract
This review examines how emerging contaminants, including microplastics, pharmaceuticals, pesticides, and industrial chemicals, may contribute to health problems and cancer risk. Evidence indicates that many of these pollutants can disrupt hormones, trigger inflammation, and cause DNA damage, though the long-term effects of low-level exposure are not yet fully understood. The authors stress the need for better monitoring, regulation, and research into how mixtures of these contaminants affect human health over time.
Emerging contaminants are growing health concerns that pose potential threats to the environment and human health globally. They originate from multiple sources, including rapid industrial processes, agriculture, households, and wastewater treatment plants. Despite efforts to reduce the levels of such pollutants, these harmful elements remain a serious problem for public health and the overall quality of life. Exposure to emerging contaminants can lead to various health problems, including cardiovascular diseases, brain and developmental disorders, and cancer. These contaminants can harm aquatic life, disrupt ecosystems, and contaminate drinking water sources. Cancer, a complex heterogeneous disease, can be triggered by multiple causes, including genetic and environmental factors. The rapid increase in emerging contaminants has contributed significantly to the development and proliferation of cancer. This review highlights the dangerous effects of exposure to these contaminants and explores future directions in research. Additionally, it summarizes the emerging roles of inorganic contaminants, such as engineered nanoparticles, and biological contaminants, including pathogenic bacteria, antibiotic-resistant bacteria and resistance genes, viruses, protein contaminants, microplastics, and nanoplastics, in cancer progression and treatment.

Microplastics and human cancer risk: A comprehensive review of environmental, molecular, and nanotoxicological perspectives
AI summary Read the abstract
This review pulls together lab research suggesting tiny plastic particles in our environment could damage cells, cause inflammation, and disrupt processes linked to cancer growth. While these findings raise real concern, scientists still lack direct proof that microplastics cause cancer in humans, so more long-term research is needed before drawing firm conclusions.
The impact of environmental microplastics as emerging carcinogens: A public health concern
AI summary Read the abstract
This review investigated the mechanisms by which microplastics may contribute to cancer development, examining studies from 2010 to 2024. Researchers found that microplastics can induce oxidative stress, inflammation, and DNA damage through multiple pathways, and that human exposure occurs primarily through ingestion, inhalation, and dermal contact. The study suggests that microplastics represent an emerging class of environmental concern warranting further investigation into their long-term health effects.
Tricks and tracks of prevalence, occurrences, treatment technologies, and challenges of mixtures of emerging contaminants in the environment: With special emphasis on microplastic
AI summary Read the abstract
This review examines how microplastics interact with other emerging contaminants like pharmaceuticals, pesticides, and industrial chemicals in soil and water, often acting as carriers that transport these pollutants into ecosystems. The combined exposure to microplastics and these toxic substances can cause cancer-promoting, hormone-disrupting, and birth-defect-causing effects in living organisms, including humans.
