Recurrent flooding near Tempe Lake, Indonesia, exacerbated by climate change, presents significant challenges for rice-farming communities, threatening their livelihoods and food security. This study explores the adaptive strategies employed farmers to mitigate flood-related risks evaluates role of institutional frameworks in risk-sharing mechanisms. Using a mixed-methods approach, we analysed primary survey data from 140 rice conducted interviews with irrigation pump operators. The viewed...
Diuron (N-(3,4-dichlorophenyl)-N,N-dimethylurea) is one among the booster biocides substituted tributyltin as an antifouling agent. It has continued to be used ever since, though little known about their levels in maritime setting of Zanzibar. This paper details occurrence and distribution diuron around coastline Zanzibar Island. The reported concentrations water ranged from Below Detection Limit 1321.67 ± 52.3 ng/L at Bwawani. Majority sites showed above Environmental Risk 430 proposed by...
In recent decades, the application of antifouling paints to watercrafts has emerged as a significant concern in coastal ecosystems, including coral reefs. Diuron, booster biocide commonly used an agent, is persistent soil, water, and groundwater. Although it exhibits moderate toxicity mammals birds, its primary breakdown product, 3,4-dichloroaniline, highly toxic environmentally persistent. The secondary Diuron emphasizes potential contaminate This investigation determined 96-hour LC50 value...
Milk is one of the very important nutrients human diet. The presence toxic elements in milk may threaten public health. This study reports levels Cadmium (Cd), Cobalt (Co) and Lead (Pb) raw cow's collected from different areas Zanzibar Island during March - May 2016. samples were analyzed by Thermo Scientific-Atomic Absorption Spectrophotometer for quantitative determination metals matrix. concentration Co this ranged ND at Mwanakwerekwe (MK1 MK2) to a maximum 0.004 mg/L Mshelishelini (MS5)...
Tributyltin (TBT) is a potent toxic chemical deliberately introduced to marine environments for combating biofoulings in structures. Several methods have been developed and used TBT analysis ecosystems. The main aim of this study was evaluate the potential silicone sheet passive sampler (SSPS) organotin species tributyltin (TBT), dibutyltin (DBT) monobutyltin (MBT) from tropical waters. conducted under laboratory based experiments then applied field trials natural coastal showed good...
In Dar es Salaam and the Coastal regions, groundwater is primary source of freshwater. Urbanization, industrialization, agricultural activities have all contributed to overuse this resource, resulting in a decline quality. study, we employ statistical analysis as means improve our understanding on Seventy-one samples squatter areas regions were used with 10 chemical parameters. Based their dominant compositions, hierarchical cluster (HCA) classified into three main clusters. The clusters...
There is a great concern about the recent use of new anti-fouling chemicals for boats and ships to coral reef health. Diuron one paints after ban organotin as an system (AFS) compound, but yet be proven safe marine environment. Presently, we demonstrated effects on fatty acid composition hard species (Fungia fungites) in laboratory. The corals were exposed different doses under short-term exposure (96 hr) (FA) compositions tissues determined using gas chromatography technique. between fresh...

Levels of Polycyclic aromatic hydrocarbons (PAHs) from sediments collected in July 2017, a week after tanks oil leak the bay Wesha Peninsular, Pemba Island are reported. Four sampling points were chosen alongside mangroves where total twenty samples during low tides. Eight PAHs detected with concentrations ranging ND to 53.42 ng/g (dw). Total was 158.38 ng⋅g-1. Phenanthrene residues (lower molecular weight) dominant followed by pyrene (higher weight PAHs) accounting for 90% and 40% detection...
Abstract Irgarol and Diuron are photosystem II inhibitor in agricultural activities antifouling paint shipping sector. A study took place at three major ports surround the Peninsular Malaysia was carried out to construct distribution of both biocides based on seasonal geographical changes. Surface seawater samples were collected during November 2011 April 2012; pretreated using solid phase extraction technique followed by quantification with GC-MS LC-MS-MS for Diuron, respectively....
