An increase of 2 °C in surface temperature is recorded in district Lahore during the last two decades. Rise of 2.2 °C and 2.4 °C surface temperature has taken place in Faisalabad and Multan Districts in the last 19 years, respectively. In the establishment of a correlation among the LST, built-up, and vegetation, there is a positive sign present in their relation. With the increase in the built-up area, LST does increase as well. Moreover, with the reduction in vegetation cover, the LST is also raised. The study has revealed that there is a need for proper planning for the durable management of urbanization.The effect of fungicides, commonly used in vine cultures, on the health of terrestrial and aquatic ecosystems has been poorly studied. The objective of this study was to evaluate the toxicity of three viticulture fungicides (myclobutanil, cymoxanil, and azoxystrobin) on non-target organisms, the bacteria Rhodopirellula rubra, Escherichia coli, Pseudomonas putida, and Arthrobacter sp., the microalgae Raphidocelis subcapitata, and the macrophyte Lemna minor. Fungicide toxicity was performed in acute cell viability assay for bacteria; 72-h and 7-day growth inhibition tests for R. subcapitata and L. minor, respectively. Contents of photosynthetic pigments and lipid peroxidation in L. minor were evaluated. Arthrobacter sp. and P. putida showed resistance to these fungicides. Even though azoxystrobin affected R. rubra and E. coli cell viability, this effect was due to the solvent used, acetone. Cell viability decrease was obtained for R. rubra exposed to cymoxanil and E. coli exposed to myclobutanil (30 min of exposure at 10 mg/L and 240 min of exposure at 46 mg/L, respectively). R. subcapitata showed about 10-fold higher sensitivity to azoxystrobin (EC50-72h = 0.25 mg/L) and cymoxanil (EC50-72h = 0.36 mg/L) than L. minor to azoxystrobin and myclobutanil (EC50-72h = 1.53 mg/L and EC50-72h = 1.89 mg/L, respectively). No lipid peroxidation was observed in L. minor after fungicide exposure, while changes of total chlorophyll were induced by azoxystrobin and myclobutanil. Our results showed that non-target aquatic organisms of different trophic levels are affected by fungicides used in viticulture.This study aimed to investigate the compression behaviors of mechanically biologically treated (MBT) wastes. For this purpose, the short-term compression-rebound and long-term compression tests were conducted on MBT wastes collected from Hangzhou Tianziling landfill in China. The results showed that the duration of immediate compression was obtained as 15.17-36.67 h and was comparable to municipal solid waste (MSW). learn more The immediate compression ratio was 0.233-0.247, and it was comparable to the aged high food waste content (HFWC)-MSW, fresh and aged low food waste content (LFWC)-MSW, but much lower than the fresh HFWC-MSW. The mechanical creep ratio (C'αc) was 0.012-0.018, being close to the fresh and aged MSWs. The bio-induced compression ratio (C'αb) was 0.143-0.174. The compression ratio rose exponentially with temperature (5-42 °C) in both mechanical creep stage and bio-induced compression stage, and it increased much faster in the bio-induced compression stage. The resilient strains was only 2.1-3.3% of the compression strain at the same stress interval, suggesting that the compression strain consisted of mostly plastic deformation and negligible elastic deformation. The above findings can provide a reference for settlement prediction and storage capacity estimation of an MBT waste landfill.Organophosphate esters (OPEs) are substances globally used as flame retardants and plasticizers that have been detected in all environmental compartments. This study aimed to evaluate the occurrence and sources of ten OPEs in the Piracicaba River Basin (Brazil). Twelve sampling sites were selected in five rivers with different pollution sources; six sampling campaigns were performed encompassing dry and wet seasons. ΣOPEs ranged from 0.12 to 6.2 μg L-1; the levels in urban areas were higher than in rural and non-urban areas, but no overall tendency concerning the seasonal effect on OPEs concentrations was observed. Tris(2-butoxyethyl) phosphate (TBOEP), tris(2-chloroisopropyl) phosphate (TCIPP), and tris(1,3-dichloroisopropyl) phosphate (TDCIPP) were the most abundant and frequently detected compounds. Nine OPEs were detected at higher concentrations in a site affected by effluents from textile industries. An acute toxicity test using Daphnia similis was performed for tris(2-ethylhexyl) phosphate (TEHP) for the calculation of a preliminary predicted no effect concentration (PNEC). The risk quotient (RQ) approach was applied and risk to aquatic environment related to TEHP levels was observed in areas adjacent to textile industries, but more toxicity studies are required for the determination of a more reliable PNEC.This study investigates the contents of lead, zinc, and cadmium in 109 near-surface soil samples collected around the abandoned mine of Fedj Lahdoum, northern Tunisia, to assess the risk of pollution they generate. The study involved some analytical procedures such as pH measurements, X-ray diffraction techniques, sequential fractionation, and geostatistical mapping using the ordinary Kriging techniques. The sequential fractionation revealed that the bioavailability of Pb, Zn, and Cd follows the orders F5 > F3 » F4 > F2 » F1, F5 > F3 » F4 » F2 > F1 and F5 > F2 » F4 > F1, respectively; their associations with organic matter and residual sulfides (F4) are relatively low. However, their high cumulated contents are dominantly associated with the residual (F5) and reducible (F3) fractions. The geostatistical mapping was endeavored to predict the spatial distribution of the studied heavy metals at unsampled sites and to produce a cumulated risk map of soil pollution. The latter is discussed with emphasis of the main factors responsible for the scattering of the pollution as much as the landscape conditions, the chemical composition of the mine tailings, the surface drainage of meteoric water and the wind. This study provides insight into the delineation of the spatial spreading of Pb, Zn, and Cd around the abandoned mine Fedj Lahdoum and their surrounding urban areas. It reveals that the mine infrastructure areas encompassing both extraction and processing and tailing deposition areas are the main sources of contamination. And the landscape conditions together with the surface drainage of meteoric water and the wind are the main factors responsible for the scattering of the pollution.
