ABSTRACT Microplastics usually refer to solid plastic particles with particle size less than 5 mm. As a new type of pollutant unavoidable produced during human production and living activities, microplastics affect the ecological environment and human health safety. Since microplastics are widely distributed, small-sized microplastics and microfibers may be introduced from ambient air, sampling equipment and laboratory equipment during various monitoring process. Strict quality control measures were required to ensure the accuracy of monitoring results. In order to evaluate the compliance of quality control measures adopted in current researches, eight quality control parameters were statistically summarized by reviewing 30 published researches involving microplastic quality control methods. The results showed that those eight quality control measures could not be fully covered in most studies and uniform standardization of some key quality control measures have not been achieved. It was suggested to develop standardized operational protocols and perform cross-calibration among laboratories. GRAPHICAL ABSTRACT

ABSTRACT Effective passivation of heavy metals in sludge is the key to achieve its land use. Potassium feldspar was modified to obtain G×K900, with a lower crystallinity, a higher specific surface area and cationic exchange capacity. G×K900 was chosen to passivate heavy metals in the sludge, and the best passivation conditions were 30% addition and a 10-day passivation period. The passivated sludge extract had no adverse effects on ryegrass germination and promoted radicle growth. The pot experiment revealed that adding 10% passivated sludge encouraged ryegrass growth while having no appreciable impact on the contents of Cu, Cr, Zn and Pb in the roots and above-ground parts compared to control treatment. The transfer factors of the four metals were all less than 1. Passivated sludge was used as a growing medium for landscaping plants, which provided a theoretical foundation for sludge land use and a resource outlet for potassium feldspar minerals.

ABSTRACT Di(2-ethylhexyl) phthalate (DEHP) is an extensively used plasticizer and being non-covalently bound to plastics it leaches out into the environment. This addresses a grave concern on its potential human exposure and subsequent deleterious effects. The ameliorative potential of Spirulina (Arthrospira platensis) against DEHP-induced toxicity was assessed in rats. Group I was control. Group II and III, were exposed to a low dose of DEHP (125 mg/kg), and Group IV and V were exposed to a high dose of DEHP (250 mg/kg). Group III and V were treated with spirulina orally (1000 mg/Kg) for 3 weeks. Exposure to DEHP elicited marked oxidative stress and associated DNA damage in a dose-dependent manner. The hepatic expression of p53 was also significantly suppressed. Liver and kidney function tests showed marked alterations. Treatment with spirulina efficaciously reversed the adverse effects. Thus, these findings offer a nutritional intervention of spirulina to combat the environmental exposure to plasticizers. GRAPHICAL ABSTRACT

ABSTRACT Airborne exposure to silica, below statutory industrial standards, can cause silica exposure and poisoning in construction workers at higher rates than predicted. This research aimed to assess the respiratory health of construction workers exposed to silica from tiles, bricks, mortar, and concrete. The study found a positive correlation between construction material dust and fume exposures and workplace seniority. Silica poisoning was dose-dependent on cumulative silica dust or fumes exposure. The average industrial silica particles and emissions BMDLs were 0.68 and 0.30 mg year/m3, respectively. Silica dust and fume BMDLs for silica poisoning were 0.02 mg/m3 and 0.01 mg/m3, respectively. The study concluded that the current exposure levels for silica in China should be re-evaluated, and operational cumulative exposure limits should be established for better prevention of silica poisoning. The study also noted that disparities in sensitivity to silica poisoning may be related to genetic factors and gene-environment interactions.

ABSTRACT Economic development brings environmental challenges of which air pollution poses serious risks to humans and ecosystems. Air pollutants include volatile organic compounds (VOCs), inorganic air pollutants (IAPs) and particulate matter (PMs). Plant leaves may reduce such air pollution through adsorption and stomatal absorption. At the same time, air pollutants enter soil and root zones due to its content in rain and leaf fall. Microorganisms degrade and transform air pollutions. However, the efficiency of phytoremediation and bioremediation is slow and the use of plant-microbe interactions may therefore greatly enhance the efficiency of phytoremediation. The release of chemicals from plants leads to a mutual interaction with the microbiome that promotes the growth of the plant itself, thus enhancing degradation and detoxification of interleaf and inter-root air pollutants. Here we review the current research progress on combined plant-microbe action and discusses the interaction between plants and associated microorganisms while providing perspectives for future research in phytotechnologies.

ABSTRACT Cadmium is a common environmental pollutant and used for industrial purposes all over the world. Cadmium exposure causes a variety of public health issues, mainly reproductive health. The present review discusses the information related to female reproductive health, including during and after pregnancy and its outcomes. Cadmium alters steroidogenesis, delays puberty, causes pregnancy loss of reproductive hormones, disturbs the menstrual cycle, causes premature births, and reduces birth weights in females. Besides that, their offspring are affected differently by prenatal mother exposure to cadmium, with more female offspring being distressed. During lactation period, nursing babies fed with milk containing cadmium causes disparity in brain physiology, reflex changes and physical immaturity. Together, these reviews highpoint the need for more studies into the consequences of cadmium exposure on reproductive health.

ABSTRACT Oxidative potential (OP) reflects integratedtoxicity of PM2.5. Therefore, OP of PM2.5 samples collected from traditional central and suburban areas (Gulou and Xianlin) in Nanjing, a megacity of China, from Jan. 2020 to Jun. 2021 was analyzed by using two abiotic assays, DTT and AA assays (OPDTT and OPAA). Values of OPDTTv and OPAAv were 0.82 ~ 3.82 and 0.15 ~ 2.22 nmol/min/m3, respectively. The OP values of PM2.5 samples collected from the Xianlin were higher than those from the Gulou by using both the DTT assay and the AA assay in this study, suggesting the seasonal and spatial variation. Moreover, OP values analyzed by using DTT assay were higher than those by using AA assay. Based on Positive Matrix Factorization (PMF), the major pollution source of the OP of PM2.5 in Nanjing was combustion source. This study may be helpful for evaluating adverse health risks of PM2.5 in a megacity.

ABSTRACT The annual cumin and perennial fennel are economically important medicinal crops of cold dry regions of Pakistan. We hypothesized that the cumin, which produces 2–3 times less biomass, will respond to lower rates of mixture of biochar with synthetic NPK fertilizer or manure, compared to fennel. The NPK, poultry manure and their mixture with wood-derived or cow manure-derived biochars were applied for three consecutive years. No positive relation between application rate of biochar-mixed fertilizers and yield of both crops was observed over three years of study, except that manure-derived biochar-NPK mixture had a positive relation (R2 = 0.99, P = 0.01) with the yield of fennel only during the third year. Significant positive influences of biochar-based fertilizers compared to control were observed for cumin and fennel of third year cropping. The co-amendment of NPK (0.14 kg ha−1) with manure-derived biochar (6.6 t ha−1) consistently increased the yield of cumin during the first two years of cropping, as opposed to NPK fertilizer. Cumin had a greater seed:stover biomass ratio when it received the co-amendment of wood-derived biochar with NPK or poultry manure. Our findings indicate that there is some potential for biochar-fertilizer amendments to improve the growth of these high-value medicinal crops.

ABSTRACT Arsenic (As) contamination is one of the most serious forms of environmental pollution caused by human activities. Numerous concerned authorities around the world are now focusing on the As decontamination. The technologies for removing As have grown in importance since it is understood that even very low amounts of As in drinking water can have serious negative effects on health. This review provides a thorough explanation of the various well-established and cutting-edge technologies, including ion exchanges, adsorption, membrane process, electrokinetic processes, electrocoagulation, precipitation, phytoremediation, inexpensive useful methods, emerging remedial techniques, nanoparticles and nano based adsorbents that can be used to remove As impurities from the drinking water. The low cost, simplicity and easy operational mechanism of adsorption technique gained much attention globally, however, it is also believed that nanotechnology will be essential in supplying clean, inexpensive water to suit human needs.

ABSTRACT In this study, activated residual Dodonaea Viscosa (ARDV) was synthesized by the simple chemical activation process as a cost-effective and sustainable adsorbent for the efficient elimination of methyl green molecule (MG) from water. The prepared ARDV was characterized by TGA, SEM, EDX, FTIR, and BET surface area analysis. The adsorption properties and mechanisms toward MG were examined using the batch method. The optimal conditions for adsorption of Pb(II) were pH= 6.6, [ARDV] =0.1 g, time=180 min, and temperature= 65°C. The adsorption isotherms and kinetics study was conducted and the resulting data fitted well with Langmuir and PSO model. The maximum sorption capacity of 99 mg/g was obtained from Langmuir isotherm for MG at 60 °C. According to thermodynamic parameters, the adsorption of MG on ARDV was endothermic and spontaneous. Hence, it could be concluded that ARDV is an inexpensive and effective bio-adsorbent for the removal of MG from polluted water.
