“…A urbanização e os processos derivados, como a impermeabilização do solo e a artificialização da drenagem natural das águas, são amplamente conhecidos como os causadores de diversos impactos ambientais (BUTLER & DAVIES, 2004;PACHECO & LIMA NETO, 2017, ARAÚJO & LIMA NETO, 2018ARAÚJO et al, 2019). Aliado aos aspectos culturais das populações locais e à dinâmica própria do ambiente natural, as bacias hidrográficas urbanas oferecem respostas compatíveis com as diversas formas de uso e ocupação do solo, bem como com a gestão do ambiente urbano (ARMITAGE & ROOSEBOOM, 2000;MARAIS & ARMITAGE, 2004;ZEILHOFER;LIMA, 2010;NEVES & TUCCI, 2011;RHEE et al, 2012;ARORA & REDDY, 2013;SIDHU et al, 2013;SILVA & PORTO, 2015).…”

Urban drainage systems can represent sources of pollutants input to the receiving bodies for which they are intended. Therefore, the present work aims to propose a tool for modeling the urban drainage system of the Vertente Marítima basin of Fortaleza, Ceará, aiming at the evaluation of bacteriological loads. For this purpose, the Stormwater Management Model (SWMM) was selected for the hydrological and hydraulic simulations; a methodology for the calculation of bacteriological loads was proposed by estimating the diffuse load [DL] (MPN, day -1 .ha -1 ) and its correlation with a series of hydro-environmental variables and scenarios for different pluviometry precipitation conditions were analyzed, as well as sewage collection and inadequately disposed solid waste (IDSW). The resultsshow that SWMM gives representative results and that the rainy season is responsible for the greater contribution of the bacteriological load to the seafront. Regarding the predictive model, a second-order potential function was adjusted by correlating DL with the average monthly precipitation (mm. day -1 ) for the three sub-basins analyzed. Subsequently, the coefficients of the equations found were correlated to IDSW (kg.day -1 ), obtaining a logarithmic adjustment (R 2 = 0.99), with which it is possible to obtain a DL estimation equation for any sub-basin of Vertente Marítima. An analysis of the scenarios showed a significant increase of the load in extreme precipitations (twice) and a considerable decrease with the increase of the fraction of the population connected to the sewage network and the decrease of IDSW production (0.28 and 0.38 times the initial value in the Jacarecanga and Maceió Stream, respectively).

“…Non-point source (NPS) pollution is the main cause of inland water deterioration and a priority issue for present water quality management worldwide [1,2]. NPS pollution is more difficult to control and to treat than pollution from point sources due to the complicated generation and formation [3,4] and concern for NPS pollution affecting lake water quality has continually increased [5,6].…”

Agricultural non-point source (NPS) pollution is a major concern for water quality management in the Soyang watershed in South Korea. Nutrients (phosphorus and nitrogen), organic matter, and sediment exports in streams were estimated in an agricultural catchment (Haean catchment) for two years. The stream water samples were taken in dry and rainy seasons to evaluate the effect of monsoonal rainfall on pollutants exports. The influence of land use changes on NPS pollution was assessed by conducting a land use census and comparing the NPS characteristic exports. Total phosphorus (TP), suspended solids (SS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD) increased dramatically in rainy seasons. Land uses were changed during the study period. Dry fields and rice paddies have decreased distinctively while orchard (apple, grape, and peach) and ginseng crops showed an increase within the catchment. The TP and SS loading decreased in the streams in 2010 compared to the loading in 2009 while the BOD and NO 3 − did not show distinct significant change. In this study, monsoonal driven rainfalls increased exports of agricultural NPS pollutants into streams. Land use change (mostly crop and paddy fields to orchards and ginseng fields) remarkably mitigated TP and SS exports into the streams.

“…Considering the characteristics of the study area, there are many commercial activities in the commercial area, and daily life in the residential area, which will generate a lot of domestic waste. Previous studies have found that the runoff from the residential area has significant concentrations of organic carbon (Rhee et al, 2012;Salim et al, 2019).…”

Human exposure to metals on road dust might have potential health risks through touching, ingesting, and inhaling. There were limited studies to link seasonal emission sources to health risks from metals on road dust. In this study, metals on road dust from different functional areas were seasonally monitored. The pollutant sources in study city varied slightly with the seasons, but the major pollutant source in the particular study site were significantly affected by the seasons. By combining the source apportionment model (PMF), line sources model and health risk models (HI: Hazard index and ILCR: Incremental Lifetime Carcinogenic risk), industrial and construction activity was identified as the crucial source of both the pollutants on road dust (29% -47%), and the HI for adults (27% -45%) and children (41% -50%) in different seasons.The traffic non-exhaust emission dominated in the carcinogenic risks for children in spring (45%) and summer (36%). Factors such as seasons, particle size, metal bioavailability, human exposure time, and exposure area were all taken into consideration to avoid overestimating or underestimating health risks. The carcinogenic risks for children (1.6 E-06) and adults (2.8 E-06) exposed to Cr both exceed the minimum threshold (10 -6 ). Measured metals mainly posed hazard to human health through ingestion route. Pb and Mn, Fe and Mn were the main harmful elements that induced non-carcinogenic risks for adults and children, respectively. Effectively identifying the source-specific health risks in different seasons will help in the formulation of adaptive strategies to diminish the potential risks.
