“…Excessive contamination by microplastics in GW can be harmful to GW microbes. GW has a diverse range of organisms, such as troglofauna (White, 1988;Breitenbach, 2008;Momot et al, 2008) and stygofauna (Huang Abundance of MPs in the groundwater (GW) of coastal areas of Bangladesh.

Groundwater (GW) plays a crucial role as the primary source of potable water in numerous developing nations. However, the increasing presence of microplastics (MPs) represents a concealed danger, threatening activities that guarantee safe drinking water in these countries. Despite this, there is limited awareness about the widespread existence of MPs in these regions of the world. In this study, we investigated the contamination levels, distribution, morphological characteristics, chemical composition, and associated public health risk of MPs in groundwater samples from six coastal districts of Bangladesh using stereomicroscopy and Fourier transform infrared spectroscopy (FTIR). MPs were prevalent at all sampling stations, with average concentrations of 24.63 ± 16.13 items/L and a range of 4–75 items/L. The majority of MPs (97.6%) were fibers, indicating a likely origin from fabric disintegration during drying, washing, discarded fishing nets, personal care items, and municipal waste. Smaller-sized MPs (<0.5 mm), transparent and violet-colored, were predominantly observed. Additionally, FTIR confirmed the presence of plastic polymers, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), ethylene vinyl acetate (EVA), and polyethylene terephthalate (PETE). Despite the high visibility observed or focus given for PETE, PE was found to be abundant. These are thought to have come from runoff from agricultural fields, seeping from landfills where plastic trash is disposed of, synthetic fabrics, and inappropriate plastic product disposal. Estimated dietary intake was recorded as 1.85 particles/person/day (i.e., 675 particles/year), suggesting the possible health risk to consumers. Hazard analyses based on the polymeric risk score revealed diverse risks associated with polymer levels, with PETE indicating a medium risk and other polymers, e.g., HDPE, LDPE, and EVA at 39%, 31%, and 17%, respectively, showing a minor risk to human health from drinking water from the studied sources. This is the first study from the regions, and the findings will be valuable for identifying sources, implementing control measures, shaping policies, and safeguarding public health against plastic pollution.

“…Furthermore, there is a growing concern about the effects of microplastic pollution on smaller organisms (microorganisms, troglofauna, and stygofauna) inhabiting in groundwater environment. 85 – 87 Yet, research on microplastic pollution in groundwater is limited to the verification of causes and subjects rather than the aftereffects or remedies to contamination. 88 , 89 Furthermore, much of the currently conducted microplastic transport modeling experiments are bounded within the laboratory that their actual application is still questionable.…”

Today the world is going through the “Plastic Age.” Nowadays, it is difficult to find a commonly used convenient item that is nonplastic. Plastic production and consumption, thus, increased exponentially and plastic emerged as one of the major concerns for waste management. Recent studies confirmed a faster rate of plastic degradation than previously believed under various conditions (e.g. saltwater, UV, soil interaction) that microplastic has become a new type of health-hazardous pollution source. Much research has been conducted since the discovery of the “Pacific Garbage Patch,” and the scope has expanded from marine to soil, groundwater, air, and food chain. This article underwent a substantial amount of literature review to verify the degree of microplastic pollution progression in major pillars of the environment (aqueous, terrestrial, airborne, bio-organism, and human). Multiple kinds of literature indicated a high possibility of vigorous interaction among the pillars that microplastic is not stationary at the point of contamination but travels across the nation (transboundary) and medium (transmedium). Thus, only the waste reduction policy (i.e. production and consumption reduction) would be effective through a single national or local effort, while pollution and contamination management require more of a collective, if not global, approach. For these characteristics, this article proposes two most urgently required actions to combat microplastic pollution: (a) global acknowledgement of microplastic as transboundary and transmedium pollution source that require international collective action and (b) standardization of microplastic related research including basic definition and experimental specification to secure global comparativeness among data analysis. Without resolving these two issues, it could be very difficult to obtain an accurate global status mapping of microplastic pollution to design effective and efficient global microplastic pollution management policies.

In light of the session documents (UNSCEAR, 2015(UNSCEAR, , 2016, presented are the results of health risk assessment in drinking water containing tritium as well as results of field observations and bioassay with algae (Lemna minor and Polyrhiza) from water bodies near radiation-dangerous industrial and scientific objects. The prospects for future studies in these areas should be associated with the assessed human radiation dose from organically bound tritium in organs and tissues of people, animals and plants;the search for plants and animals selectively accumulating tritium and its subsequent bioassay in water. It is necessary to develop the approaches to harmonization of tritium standards in water objects and potable water, in particular. Sanitary and hygiene standards are suggested to develop on the basis of health risk assessment in drinking water with tritium. The upcoming trend for assessing the contribution of organically bound tritium to the total human radiation dose is the local irradiation by tritium incorporated into DNA of cells and tissues and radiosensitive organs. The well-known and new methods of microdosimetry of DNA incorporated radionuclides are necessary to solve this problem.Keywords: natural and technogenic tritium, water biomonitoring, Lemna minor, Spirodela polyrhiza, health risk assessment, drinking water, the interventional level for tritium.
