Despite the existence of an effective vaccine, recent sporadic YF epidemics have underscored concerns about sylvatic vector surveillance, as very little is known about their spatial distribution. Here, we model and map the environmental suitability of YF’s main vectors in Brazil, Haemagogus spp. and Sabethes spp., and use human population and NHP data to identify locations prone to transmission and spillover risk. Methodology/Principal findings We compiled a comprehensive set of occurrence records on Hg. janthinomys, Hg. leucocelaenus, and Sabethes spp. from 1991–2019 using primary and secondary data sources. Linking these data with selected environmental and land-cover variables, we adopted a stacked regression ensemble modelling approach (elastic-net regularized GLM, extreme gradient...

Analysis of Pb content in suspended solid was mesured at Laboratory of Environmental Health and Disease Control Engineering Center (BTKLPP) in North Sumatra Province. Pb content in suspended solid at high tide ranged from <0,02-0,06 mg/l and at low tide ranged from 0,02-0,065 mg/l. The content of dissolved Pb at high tide ranged from 0,210-0,651 mg/l and at low tide ranged from 0,288-0,750 mg/l. Content of Pb in the waters of Belawan Port has passed quality standard of the Minister of Environment of Republic Indonesia that means the Harbour area is polluted and improper for drinking water as well as for fish cultivation.
