C environment and promoting superior practices in the development and implementation
C atmosphere and promoting good practices inside the improvement and implementation of indicator systems with regards to this urban challenge. two. Components and Solutions 2.1. Predicted Environmental Concentration Calculation–PEC The PEC calculation of surface water of Santos Bay was performed as outlined by the EMEA guideline [26], working with the following Equation (1) Maximum daily dose consumed per inhabitant Mpen Quantity liquid wasteL inhabitantPEC Sur f ace Waters =(1)daydilution f actorconsidering: Mpen = Tasisulam Technical Information market place penetration issue, Mpen [26], was calculated based on Equation (two) Mpen = Consumption (mg/year ) 100 DDD (mg/inhabitant/day) Pop 365 days (2)considering: DDD = defined each day dose, based on the World Overall health Organization (WHO) Pop = number of the city inhabitants Contemplating that the WWTP of Santos receives discharges in the cities of Santos and S Vicente, information have been obtained from each cities [235]. Based on the Brazilian Institute of Geography and Statistics data [19], the Santos population in 2018 was 432,957 inhabitants, along with the S Vicente population was 363,173 inhabitants, Streptonigrin Biological Activity totalling 796,130 inhabitants. Based on the fundamental Sanitation Business of S Paulo State [25], the level of liquid waste/inhabitant/day is 575 L. The dilution issue utilized is 10, and as a result, the following values of Mpen and PEC have been obtained and are included in Table 1. Information relating to the number of distributed ARVs was obtained via access towards the Federal Government site [27], exactly where, through the Law on Access to Information (LAI) No. 12527/2011, annual withdrawal data had been requested for the antiretroviral drugs dispensed in Santos and S Vicente municipalities, from July 2017 to July 2018. Liquid waste generation information were collected together with the publications obtainable on the web from SABESP and Environmental Protection Agency from the State of S Paulo [24].Resources 2021, ten,four ofTable 1.

Ecotoxicological Assessment An EMEA [26] document establishes that in the event the PEC value is equal to or above 0.01 L-1 , then the environmental fate ought to be investigated and effect assessment carried out. In this sense, toxicity tests had been performed to assess the acute (fertilization rate) and chronic (embryo arval improvement) effects making use of sea urchins (Echinometra lucunter), with three selected ARVs that presented PEC values above 0.01 L-1 : atazanavir (NortecLab, Duque de Caxias, Rio de Janeiro, Brazil), nevirapine and efavirenz (Farmanguinhos, Fio CruzLab, Manguinhos, Rio de Janeiro, Brazil). The organisms had been collected via totally free diving, at Ilha das Palmas, within the municipality of Guaruj S Paulo state, stored inside a thermal box, and covered using the algae genus Ulva sp. The temperature conditions were maintained till transport to the laboratory, exactly where they have been kept in a tank, beneath strong aeration and excellent conditions, till the time of testing. T.
