Abstract A new approach was carried out with the spent mushroom substrate (SMS) of Pleurotus florida on ferrous iron (Fe2+) removal using live, dead and pretreated substrate. In this study, the various dosage levels of SMS namely, 0.25, 0.50, 1.0 and 1.50 g/50 mL were used for the removal of Fe2+ at different time intervals for 90 min. The effect of various temperatures and pH on Fe2+ removal was studied with optimized dosages and time intervals. The biosorption potential of P. florida SMS was checked against the iron-contaminated groundwater collected from in and around Salem, Namakkal and Dharmapuri districts of Tamil Nadu. The biosorption data were obtained and analyzed in terms of their kinetic behavior. Among the SMS of P. florida, the live SMS showed potential Fe2+ removal (100%) from aqueous metal solution in all the tested concentrations. SMS of P. florida showed high potential removal of Fe2+ in neutral pH, at room temperature and explored an efficient sorption ability (100%) in the tested water sample (SW10). The adsorption kinetic values fitted very well with pseudo-second-order when comparing with pseudo-first-order reaction. FTIR, SEM and EDX analysis proved the accumulation of Fe2+ by the SMS. The present study confirmed that the live SMS of P. florida may serve as a potential and eco-friendly biosorbent for removal of Fe2+ from the iron-contaminated water. Graphic abstract

Rising cases of environmental mercury hazards has led to a need for cost-effective mercury treatment techniques. Extensive use of mercury from ancient times has resulted in water contamination that may require remediation. Mercury contamination is tedious to treat and may pose a risk to human health and the environment. To deal with this threat of mercury contamination, industrial wastes and wastewaters containing mercury requires treatment for its removal and immobilization. This chapter provides a synopsis of the availability, performance, and technologies for management of mercury in water. It covers the innovative methods to treat the mercury contamination like biosorption. In this chapter, the technological aspects available for the mercury treatment technologies are reviewed. It describes the theory, design, and operation of the technologies; provides information on commercial availability and use; and includes data on performance, where available.

Scientific Opinion

A mini review of the toxicity of Thallium (Tl) at low doses is herein presented. Thallium has severe toxicity. Although its acute biological effects have been widely investigated and are well known, its biological effects on human health and in cell cultures at low doses (<100 μg/L) due, for example, to Tl chronic exposure via consumption of contaminated water or foods, have often been overlooked or underestimated. Relatively few papers have been published on this topic and are herein reviewed to provide a focused scientific opinion in the light of current worldwide regulatory issues.

<p>The use of untreated municipal wastewaters for irrigating agricultural crops negatively affects human health. Thus, the sewage effluent from the city of Pachuca, in the state of Hidalgo, Mexico, used for agricultural purposes was the most important reason to undertake this research work, whose main objective was to understand the process that involves its current use as irrigation water, and the potential harm to human health because the raw vegetables produced using this irrigation scheme are being consumed by the general public. The content of fecal coliforms and helminth eggs in wastewaters were determined and the level of parasitological contamination of vegetables and the potential number of people affected was estimated due to the consumption of raw produce without proper pretreatment, a common practice in Mexico. The potential level of parasitological contamination of vegetables was estimated by analyzing bibliographic data collected under similar climatic and technological conditions as in Pachuca. Results indicate that the level of wastewater contamination from fecal coliforms in Pachuca was 5000 times higher than the maximum permissible level based on Mexican standards for irrigation waters, and for <em>Ascaris lumbricoides</em> L. and <em>Hymenolepis diminuta</em> (Rudolphi) eggs up to 64 times. The number of persons potentially infected through consumption of raw vegetables irrigated with this contaminated water was estimated to be 169,000 annually.</p>

Zoonoses contribute an estimated 75% of new or re-emerging infectious diseases in humans with Covid-19 being the latest addition. Carnivores act as definitive hosts and reservoirs for several endoparasites with varied effects on human health. These interactions are fluctuating and adaptive, changing in response to various biotic and abiotic conditions. With the development of ‘One health movement’ more focus has been laid on zoonotic infections and their management. The present study showed that carnivores of Dampa Tiger Reserve (DTR) are host to several infectious parasites with a prevalence rate of 90.47%. Families like Felidae, Canidae, and Viverridae were found to host the maximum number of parasites. The parasite Paragonimus spp. were recorded to be present in the highest number (33 nos.) of scat samples followed by <i>Strongyle spp</i>. (27 nos.), <i>Ascaris lumbricoides</i> (23 nos.), and <i>Isospora spp</i>. (19 nos.). These parasites are known to infect humans through different modes like faecal-oral route, uncooked meat, fishes, and contaminated water and induced health implications like inflammatory in the brain, bronchitis, covert toxocariasis, acute lung inflammation etc. As the surrounding landscape of DTR continuous to shrink and humans are more prone to these parasites through their daily activities and lifestyle, the study will be crucial for providing a platform for future epidemiological study and diseases management in the region.

Lead-contaminated water, soil, and air have been perceived as potential sources of lead exposure for a considerable length of time, which continues to threaten human health; particularly that of young children. An Integrated Exposure, Uptake, and Biokinetic (IEUBK) as a human health risk model were applied to predict the Blood lead levels (BLLs) in children. A variety of data for air, soil, and water were obtained from the industrial region in Al-Dorah city in Baghdad for the period 2012- 2014. The result found that the predicted BLLs value of 11.17 μg/dL obtained from the IEUBK model was exceeding the agency’s threshold of concern of 10 μg/jdL which was considered as the lowest level of concern for BLL in children, this result of the IEUBK model was in agreement with the actual value of BLLs which were taken from previous literature for 24 blood samples of school children matched for age curried out in the same Al-Dorah region. This technique propels logical comprehension of the connection between BLLs in children and environmental media in both air and soil for the pollute condition. It can control national health-based benchmarks for lead and related community public health decisions.

Even though the human being cannot live without water it has the negative effect on human health too. Its effect depends on the quality of water which human beings drink. The contaminated water used by human beings may degrade human health with the help of some toxic substances, like, fluoride, arsenic, mercury, lead etc. The poor people are prone to suffer from these toxic substances although they, generally, cannot afford for the water of good quality for drinking and washing. Moreover, there is a lot of water-washed diseases, water based diseases, water born diseases etc. which affect human health. These diseases and toxic substances increase health expenditure of the people. Therefore, contaminated water forces the poor people to stay in the vicious circle of poverty if they use it. This paper will analyze water, poverty and health expenditure nexus.
