“…As MPs are an organic carbon (around ~80%), no significant methods have been developed yet to distinguish soil organic carbon and MPs carbon, and as MPs come in contact with the soil matrix, it forms the MPs cycle (i.e., slow MPs/NPs A comprehensive approach requires balancing human well-being with nature's services; although it is one of the basic essences behind the development of ecosystem services, it has yet to be investigated despite being emphasized in the late 1990s [140,[148][149][150][151]. In this section, emphasis is given to connect the dots among the micro or nano plastics, ecosystem services, and human well-being; we do not delve into the fundamentals of the functionality of the natural systems, which is already available in various literature [44,48,152,153]. Ecosystem services as an established concept connect ecological science with the economics and social sciences.…”

“…On a larger scale, hindering pollination will lead to a decrease in seed banks; the worst affected species might be endemic or rare ones with limited viable seed banks, because, to a large extent, pollination is more prone to local extinction [170]. Since MPs and NPs are abundant in the tropical region, which is coincidentally the most diverse region with a high number of endemic and rare plant species, therefore, hypothetically, MPs and NPs pose a serious threat to the plant diversity in the tropics [48,137,149]. Similar to other pollutants, humans inhale MPs; therefore, the continuous inhalation of MPs leads to serious health concerns including lung congestion, cancer, ulcers, and several other nasal and olfactory infections [164].…”

“…As stated above, ample quantities of plastics reach marine ecosystems; therefore, urgent efforts are needed to protect oceans for better marine health, which are critical for achieving several other SDGs, including food security and hunger. Plastic waste mismanagement is affecting the terrestrial ecosystems [47,264]; however, a large number of research studies are reported for aquatic ecosystems [44,48,118]. About 80% of the MPs pollution is derived from land-based sources, and it is estimated that there will be a significant increase in use of MPs in the terrestrial ecosystems [47,265].…”

Plastic pollution is ubiquitous in terrestrial and aquatic ecosystems. Plastic waste exposed to the environment creates problems and is of significant concern for all life forms. Plastic production and accumulation in the natural environment are occurring at an unprecedented rate due to indiscriminate use, inadequate recycling, and deposits in landfills. In 2019, the global production of plastic was at 370 million tons, with only 9% of it being recycled, 12% being incinerated, and the remaining left in the environment or landfills. The leakage of plastic wastes into terrestrial and aquatic ecosystems is occurring at an unprecedented rate. The management of plastic waste is a challenging problem for researchers, policymakers, citizens, and other stakeholders. Therefore, here, we summarize the current understanding and concerns of plastics pollution (microplastics or nanoplastics) on natural ecosystems. The overall goal of this review is to provide background assessment on the adverse effects of plastic pollution on natural ecosystems; interlink the management of plastic pollution with sustainable development goals; address the policy initiatives under transdisciplinary approaches through life cycle assessment, circular economy, and sustainability; identify the knowledge gaps; and provide current policy recommendations. Plastic waste management through community involvement and socio-economic inputs in different countries are presented and discussed. Plastic ban policies and public awareness are likely the major mitigation interventions. The need for life cycle assessment and circularity to assess the potential environmental impacts and resources used throughout a plastic product’s life span is emphasized. Innovations are needed to reduce, reuse, recycle, and recover plastics and find eco-friendly replacements for plastics. Empowering and educating communities and citizens to act collectively to minimize plastic pollution and use alternative options for plastics must be promoted and enforced. Plastic pollution is a global concern that must be addressed collectively with the utmost priority.

Plastic particles smaller than 5 mm, i.e., microplastics, have been detected in a number of environments. The number of studies on microplastics in marine environments, fresh water, wastewater, the atmosphere, and the human body are increasing along with a rise in the amounts of plastic materials introduced into the environment every year, all contributing to a range of health and environmental issues. Although the use of primary microplastics has been gradually reduced by recent legislation in many countries, new knowledge and data on these problems are needed to understand the overall lifecycle of secondary microplastics in particular. The aim of this review is to provide unified information on the pathways of microplastics into the environment, their degradation, and related legislation, with a special focus on the methods of their sampling, determination, and instrumental analysis. To deal with the health and environmental issues associated with the abundance of microplastics in the environment, researchers should focus on agreeing on a uniform methodology to determine the gravity of the problem through obtaining comparable data, thus leading to new and stricter legislation enforcing more sustainable plastic production and recycling, and hopefully contributing to reversing the trend of high amounts of microplastics worldwide.

Studies investigating microplastics, pharmaceuticals, and pesticides as contaminants of emerging concern (CECs) in surface water sources in Kenya are reviewed. Contaminants of emerging concern are chemicals that have recently been discovered that may pose a threat to the environment, aquatic life, and human life. Microplastics in surface waters range from 1.56 to as high as 4520 particles/m3, with high concentrations recorded in coastal waters. The dominant microplastics are fibers, fragments, and films, with foams, granules, and pellets making up only a small percentage. The main source of pharmaceuticals in water sources is not wastewater‐treatment plants but rather raw untreated sewage because high concentrations are found near informal settlements with poor sewage connectivity. Antibiotics are detected in the range of the limit of quantification to 320 μg/L, with sulfamethoxazole, trimethoprim, and ciprofloxacin being the most abundant antibiotics. The high frequency of detection is attributed to the general misuse of antibiotics in the country. A health risk assessment indicated that only ciprofloxacin and acetaminophen posed noncarcinogenic health risks in the Ndarugo River and Mombasa periurban creeks, respectively. Similarly, the detection of antiretroviral drugs, mainly lamivudine, nevirapine, and zidovudine, is associated with human immunodeficiency virus prevalence in Kenya. In the Lake Naivasha, Nairobi River, and Lake Victoria basins, frequently detected organochloride pesticides (OCPs) are methoxychlor, alachlor, endrin, dieldrin, endosulfan, endosulfan sulfate, α‐hexachlorocyclohexane (α‐HCH), γ‐HCH, and dichlorodiphenyltrichloroethane (DDT), some of which occur above permissible concentrations. The presence of DDT in some sites translates to illegal use or historical application. The majority of individual OCPs posed no noncarcinogenic health risk, except dieldrin and aldrin which had a hazard quotient >1 in two sites. Therefore, more surveying and regular monitoring in different regions in Kenya concerning CECs is essential to determine the spatial variability and effective measures to be taken to reduce pollution.
