A direction is suggested for future development in the field of estimation of water pollution assessment through geospatial techniques.The relationship between diabetes mellitus and short-term exposure to extreme temperatures remains controversial. A systematic review and meta-analysis were performed to assess the association between extreme temperatures and diabetes mellitus morbidity and mortality. PubMed, Embase, the Cochrane Library, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched since inception to January 1, 2019, and updated on November 17, 2020. The results were combined using random effects model and reported as relative risk (RR) with 95% confidence interval (CI). In total, 32 studies met the inclusion criteria. (1) Both heat and cold exposures have impact on diabetes. (2) For heat exposure, the subgroup analysis revealed that the effect on diabetes mortality (RR=1.139, 95% CI 1.089-1.192) was higher than morbidity (RR=1.012, 95% CI 1.004-1.019). (3) With the increase of definition threshold, the impact of heat exposure on diabetes rose. (4) A stronger association between heat exposure and diabetes was observed in the elderly (≥ 60 years old) (RR=1.040, 95% CI 1.017-1.064). In conclusion, short-term exposure to both heat and cold temperatures has impact on diabetes. The elderly is the vulnerable population of diabetes exposure to heat temperature. Developing definitions of heatwaves at the regional level are suggested.The suitable temperature of circulating cooling water is conducive to the reproduction of bacteria, which will cause corrosion to the pipe and form slime on its surface. Therefore, the sterilization of circulating cooling water is an essential step. In this work, a new type of SA-CuZnO@ODA-GO composite antibacterial material with hydrophobic properties was prepared by ultrasonic treatment method. The composite was characterized and analyzed by SEM, TEM, XPS, XRD, and FT-IR. Then, the CuZnO@ODA-GO@PU hydrophobic and antibacterial coating was prepared. The antibacterial properties and mechanism of the composite were investigated by gram-positive bacteria S. aureus and gram-negative bacteria E. coli. The result shows that the best antibacterial rate of SA-CuZnO@ODA-GO composite antibacterial material is up to 99.10%. As for the SA-CuZnO@ODA-GO@PU composite antibacterial coating, the corrosion resistance of the antibacterial coating is up to 99.99%. The anticorrosion property is due to the hydrophobic modification of the composite, which can insulate the steel sheet from water. Secondly, due to the rigidity of the SA-CuZnO@ODA-GO, it combines with epoxy resin to form a compact structure.Due to the genotoxic, carcinogenic and teratogenic mechanism of action, anticancer drugs are highly hazardous compounds. Their occurrence, fate, and effects in the environment have not been systematically studied as compared to other medicaments. Therefore, reliable data, including their stability and persistency, is required in order to assess it. Epacadostat cell line Taking into account, that hydrolysis is one of the most important factors regarding stability of chemicals in water, the aim of our study was to investigate the hydrolytic stability of five commonly used anticancer drugs (ifosfamide, cyclophosphamide, 5-fluorouracil, imatinib, and methotrexate) and one metabolite (7-hydroxymethotrexate), as the systematized and coherent data available is limited. The hydrolysis studies have been prepared according to the OECD 111 procedure to obtain standardized and comparable results. The preliminary tests at pH 4, 7, and 9 and 50 °C show that only cyclophosphamide and ifosfamide are unstable, whereas the estimated t1/2 at 25 °C is >1 year for other investigated compounds. Moreover, much more detailed experiments were performed and indicate that at environmentally relevant temperatures, cyclophosphamide, and ifosfamide would be quite persistent in the terms of hy
