Nano and microplastics occurrence in wastewater treatment plants: A comprehensive understanding of microplastics fragmentation and their removal

Chemosphere, Journal Year: 2023, Volume and Issue: 334, P. 139011 - 139011

Nano/microplastic (NP/MP) pollution is a growing concern for the water environment. Wastewater treatment plants (WWTPs) are considered major recipients of MP before discharging into local waterbodies. MPs enter WWTPs mainly from synthetic fibers through washing activities and personal care products. To control prevent NP/MP pollution, it essential to have comprehensive understanding their characteristics, fragmentation mechanisms, effectiveness current processes used in removal. Therefore, objectives this study (i) understand detailed mapping WWTP, (ii) mechanisms NP, (iii) investigate removal efficiency by existing WWTP. This found that fiber dominant shape MP, polyethylene, polypropylene, polyethylene terephthalate, polystyrene polymer type wastewater samples. Crack propagation mechanical breakdown due shear forces induced facilities (e.g., pumping, mixing, bubbling) could be causes NP generation Conventional ineffective complete MPs. Although these capable removing ∼95% MPs, they tend accumulate sludge. Thus, significant number may still released environment on daily basis. suggested using DAF process primary unit can an effective strategy initial stage goes secondary tertiary stage.

Published: July 1, 2023

Endocrine-disrupting chemicals (EDCs) are a growing public health concern worldwide. Consumption of foodstuffs is currently thought to be one the principal exposure routes EDCs. However, alternative ways human through inhalation and dermal contact. These compounds in food products such as canned food, bottled water, dairy products, fish, meat, egg, vegetables ubiquitous general population. Therefore, understanding EDCs' properties, origin, exposure, toxicological impact, legal aspects vital control their release environment food. The present paper provides an overview EDCs possible disrupting impact on endocrine system other organs.

Semen quality represents a compelling factor for fertility, and delineating the normal values has proven difficult. In last four decades, several authors have reported noticeable decline in sperm parameters. Also, studies investigating ‘time to pregnancy’ shown that fecundity begins be reduced when numbers decrease below 30 million, even though according 6th edition of WHO manual, value is currently 16 million/mL or 39 million per ejaculate. There exists sufficient data suggest counts over time, clear reason this adverse trend not well established, but some associations been hypothesised, such as maternal smoking during pregnancy. Additional potential factors yet fully illustrated involve poor diet, increased obesity, exposure environmental toxins. Moreover, change conditions more common endocrine-disrupting chemicals (EDCs), pesticides herbicides, bisphenol A, phthalates, polychlorinated biphenyls, heavy metals, starting from prenatal life continuing into adulthood, may exhibit probable features explaining reduction Therefore, main goal narrative review furnish an overview possible effects EDCs on testicular function spermatogenesis and, also, summarise evidence regarding examine its consequences.

Phthalate esters (PEs) are by far the most produced and extensively used synthetic organic chemicals with notable applications in many industrial products such as vinyl upholstery, adhesives, food containers, packaging materials, printing inks, cosmetics, paints, pharmaceuticals munitions, insecticides among other. PEs have long been recognised ubiquitous pollutants of prime environmental concern, urbanisation amongst main cause source these compounds. Due to their notoriety, compounds known pose devastating effects living organisms including humans. The presence metabolites aquatic ecosystems is concern primarily due endocrine disrupting carcinogenicity properties. Several research studies reported prevalence, exposure pathways, toxicity, impacts Their principal routes could be direct or indirect, which route include contact, eating, drinking contaminated foods, indirect constitute aerosols, leaching other forms contamination. find way into water systems through means effluent discharges, urban agricultural land runoff, from waste dumps diffuse sources. High-end instrumentation improved methodologies on hand resulted increased ability measure trace levels (μg/L) different matrices ecological compartments lakes, oceans, rivers, sediments, wetlands samples. In light above, this article provides an informed focused information prevalence phthalate related Furthermore, techniques that enabled extraction analysis samples also explained.
