Abstract The physicochemical properties and phytoplankton community structure were investigated seasonally at four stations representing Northwest El-Manzala Lake, Egypt, during 2019. Results indicated wide local and seasonal variations in the concentrations of various physicochemical parameters. There was a noticeable variation in levels of nitrogen and phosphorus forms; higher ammonia, nitrite, and nitrate contents of 11.6 (in autumn), 2.28 (in winter), and 2.32 mg L-1 (in autumn), respectively, were detected at Shatt Greba (site IV). Total-P and ortho-P exhibited higher levels of 7.14 and 0.96 mg L−1, respectively, at site IV in summer. The greatest amounts of sodium, potassium, calcium, barium, and lithium were 102.88 g L−1, 9.12 g L−1, 8.56 g L−1, 345.8 mg L−1, and 1.62 mg L−1, respectively, during summer. Two-way ANOVA presented a highly significant local and seasonal effect of physicochemical parameters on phytoplankton biomass. There were high levels of autumn algal biomass (65.96 mg L−1) and low levels of winter algal biomass (32.28 mg L−1). Cyanophyta, Chlorophyta, and Pyrrophyta dominated in the autumn, whereas Bacillariophyta dominated in the winter. Cyanophyta and Pyrrophyta biomass showed high local variations in contrast to Bacillariophyta and Chlorophyta. The species diversity index revealed that the study area was mildly to moderately polluted water.

Groundwater samples were collected in Erode city, Tamilnadu, from an area having large number of textile dyeing units. Though people residing in this area use river water supplied by local bodies as their major source for drinking, groundwater is also used as complementary source. The samples collected were subjected to systematic analysis using the standard methods and procedures. The values obtained for different physicochemical parameters were compared with the standard values given by ISI/ WHO. Variations in many physicochemical parameters were observed for most of the samples when compared to the standard values. More than half of the samples collected had their EC, TDS, total hardness, calcium, magnesium, sulphate and chloride exceeding their acceptable limits. This attempt has been made to determine the quality of groundwater in the study area confirms the deterioration of groundwater quality in the area and calls for some effective measures to be taken urgently to minimize the adverse impacts that may occur due to the contamination of groundwater.

Background: The present study investigated the concentrations of lead, nickel, copper, zinc, their toxicity potential, and their ecological hazard in surface soils of Hamedan City, Iran. Also, using the Bio-concentration Factor (BCF), concentration Comprehensive Bio-concentration Index (CBCI), and Metal Accumulation Index (MAI), was evaluated the ability of some tree and shrub species to absorb heavy metals in soil and air. Methods: Sampling of leaves of nine tree species and shrubs (plane, acacia, elm, willow, mulberry, ash, redbud, pine, and cypress) was performed in six stations. After preparation and acid digestion of the samples, the concentrations of heavy metals were determined using an atomic absorption spectrometer. Results: The trend of changes in soil heavy Mean±SD metal concentrations was in the order of nickel> zinc> copper> lead in the amounts of 61.41±11.34˃ 43.04±14.4˃ 42.87±8.36˃ 18.77±6.51 mg/kg. Evaluation of acute toxicity potential indicators and ecological risk of heavy metals indicated low soil pollution status. Findings of BCF, CBCI, and MAI ndices in the leaves of the species showed that the highest levels of BCF of heavy metals, i.e., zinc, copper, lead, and nickel, were in willow, elm, cypress, and pine species, respectively. Results show that heavy metal accumulation in different species. Conclusion: Depends on soil type, tree species, climatic conditions, type of pollutant source, species age, and other factors. In this study, elm and acacia have the highest ability to absorb heavy metals from soil and air.

Abstract Since 2006 the domestic popularity and sales of electronic cigarettes (i.e., electronic nicotine delivery systems or ENDS) have grown rapidly. Although the constituents of the aerosol produced by ENDS have been previously investigated, differences in puff regimens and aerosol trapping schema in published literature often complicate result comparisons and data interpretation. As the ENDS product designs continue to evolve, there is a critical need to develop and validate robust methodologies for laboratory testing, appropriate aerosol generation and trapping media required for accurate determinations of ENDS aerosol metals deliveries. A simple, high metals purity, fluoropolymer trap was developed and validated that meets standard machine puffing regimen (CORESTA Recommended Method 81) specifications and exhibits negligible acid extractable metal backgrounds. Using a standard machine puffing regimen in combination with a fluoropolymer condensation trap, aerosol was generated and collected from select ENDS devices for analysis of chromium, nickel, copper, zinc, cadmium, tin, and lead with triple quadrupole inductively coupled plasma mass spectrometry. Devices tested spanned a range of commercial products, including flavored variants of JUUL pods, refillable tank systems, rechargeable cartridges, and single-use ENDs devices. Results showed that for aerosols generated under a fixed puffing regimen (50 puffs/collection), metal concentrations ranged from below the detection limits (LOD) to 614 ng copper and 339 ng zinc per 10 puffs. Cadmium concentrations were below LOD for all devices tested. Device specific aerosol levels of Sn and Pb ranged from below LOD to low nanogram levels. Cr and Ni were transported in aerosols at levels equivalent to, or slightly higher than in mainstream cigarette smoke using a standard smoking regimen. The generally lower levels of specific metals, Cd and Pb, transmitted in ENDS aerosols compared to mainstream cigarette smoke reflect possible reduction of harm for smokers who substitute the use of ENDS as cessation devices in place of smoking cigarettes.
