Abstract

Banyuurip is one village in East Java that has successfully replanting its mangrove forest. Mangrove forest in Banyuurip had experienced losses due to changes into aquaculture and also abrasion from the Java Sea. However, with the concern and willingness of local fishermen who realized the loss of mangrove brought significant impact to their fish catching, mangrove replanting was carried out since 2007. This effort went well because they did the seedling process by themselves. Seedling process in Banyuurip is dominated by mangrove Avicennia sp and Rhizophora because these mangroves are found in high numbers in Banyuurip. Seedling is carried out using polybag and the germination was conducted in an area called ‘bedengan’ to protect the seeds from the sun. The seeds are watered using water pump regularly and supervision is conducted to prevent the seeds from being eaten by crab. At present, mangrove seedling in Banyuurip is running well and the seeds are either used by themselves or are selling to another mangrove places.

Abstract

HighlightsConcentration of lead (Pb) in the surface water and sediment were analyzedThe ecological risks of metal in the ecosystem were assessedPb concentration in the surface water and sediment were observed in the similar range Pb in the study areas has low ecological risk indexConcern on Pb contamination in Prigi Harbor is neededAbstractThis study attempts to measure the spatial distribution of Pb in the seawater and surface sediments and to analyze its potential harmful effect in the surface sediments of the coastal areas of Prigi Bay, Trenggalek. Prigi Bay has been considered as one of the harbors with substantial activities from fisheries, tourism, and domestic events in Indonesia. These activities may discharge heavy metals, e.g., lead (Pb) into the environment and bring hazard to animal and human life. Data for Pb concentrations were collected from two stations near Prigi Harbor (Stations 1 and 2), one station in the Prigi Beach (Station 3) and two stations near the river mouths (Stations 4 and 5). Water quality parameters (temperature, salinity, pH, and DO) were also measured. Stations 1 and 4 displayed a higher concentration of Pb in the seawater than in the surface sediments. On the other hand, Stations 3 and 5 showed a higher concentration of Pb in the surface sediments than in the seawater. Pb concentration in the seawater was 0.22-0.60 mg/kg, and in the surface, sediments were in the range of 0.40-0.57 mg/kg. According to the analysis of contamination factor (CF), the study sites have a low degree of contamination from heavy metal Pb (CF < 1). The result was also supported by the potential toxicity of Pb to the benthic environment around Prigi Bay that was still considered low (E < 40). In spite of the low degree of contamination and low potential toxicity from Pb, concern regarding the heavy metal pollution in the study areas is still needed due to substantial activities that can contribute to the accumulation of heavy metal in a long time.
