Abstract Vary heavy metals scattered in suspension loads and re-sedimentation from the tailing of the offshore-alluvial tin mining at Tanah Merah and its surroundings, Central Bangka Regency. Research is needed to determine the type, composition, spatial distribution of heavy metals, and potential pollution. The active surface-sediments were taken from shallow marine systematically around the offshore tin mining area in the east season. Geochemical analysis of sediment using x-ray fluorescence, coupled with minerals and sieve analysis, and support by spatial analysis. These sediments have dominant the sand-size (range very-fine sand to coarse sand) and silt, contained predominantly large quantities of quartz minerals and shell fragments of marine animals. The metals are in the following decreasing order: Cr>Zn>Pb>Ni>Cu>As>Co>Cd. The spatial distribution of heavy metals generally has a relatively south, east, and north position, with concentrations occurring along the coastline and showing the degradation composition towards the open sea. The marine sediments are uncontaminated to moderately contaminated by Cd and Pb, indicate both natural and anthropogenic enrichment, low the pollution load index (PLI), and have various potential ecological risks index (RI) (low to very high RI).

Development Direction

The rational planning of urban spatial distribution and development direction could benefit the urban economy, social environment and other aspects, as an essential part of urban planning. Since the Law of EIA promulgated in 2003, the scope of environmental impact assessment has been upgraded to a higher level of overall urban planning whereas the influence is not significant. In 2018, urban and rural planning function was merged into the Ministry of Natural Resources, from leading urban construction to serving the protection of urban natural resources. It is also a new and significant approach to analyse the rationality of urban spatial distribution and development direction from the perspective of environmental impact assessment. The purpose of Jianghua Yao autonomous county is to build an eco-tourism civilized city, which is representative in the selection of cities for environmental impact assessment. On the space structure of functional areas and the development direction to the indicator elements of Yao nationality autonomous county class was divided into 4 categories, 5 layers,15 index factors were selected to construct the environmental impact assessment index system. Using analytic hierarchy process (AHP) to select the indexes weights assignment, then according to the evaluation criterion to evaluate it, we draws the analysis conclusion in the environment aspect. The planned urban spatial distribution and development direction of Jianghua Yao autonomous county from 2014 to 2020 are reasonable, have little negative impact on the environment, and are suitable for the green development of the city.

Artisanal and small gold mining activity in Wonogiri Regency has long been done with problems on environmental quality. This study was aimed to analyze the levels and spatial distribution of heavy metals in the mining area. Survey of  mining and amalgamation sites, sampling the soil and tailings had been conducted. There were 66 samples of soil and tailing were collected, analysis of heavy Fe, Mn, Pb, Hg, As and Co, using X-ray fluorescence (XRF). Normal distribution test of data was conducted using the Kolmogorov-Smirnov and Shapiro Wilk.  The spatial distribution of heavy metals was described using Krigging method. Contents of most heavy metals in the area studied were high, except for Co. According to the distribution pattern of heavy metals indicated that the contamination caused by the mining.
