Abstract

Indonesia’s target to be a new industrial country makes a wide chance in the developing of many industrial sectors. The main problem is the disruption of environmental balance due to poorly managed liquid waste released by the industry. Heavy metal such as chromium (Cr) is the typical pollutant generated from tannery industry in Indonesia. Toxicity test of desorbed chromium ions from polluted soil around tannery industry in Yogyakarta-Indonesia by using Brassica junceaand Helianthus annuus L.has been carried out. In this research, soil samples were dividedinto four sample points based on the distances from the waste water point sources. Metal content and some physico-chemical properties including ash content, total organic carbon, and cation exchange capacity were determined in this study. Furthermore, the chromium ions adsorption and desorption from polluted soils were investigated and measured by atomic adsorption spectrophotometry (AAS). Thus, ecotoxicity testsof soil eluates from desorption experiments wereperformed with Brassica junceaand Helianthus annuus L.The resultsshowed that sample III had the highestCr content at916mgkg–1.The adsorption isotherm of Cr ions into soils followed Langmuir isotherm with the highest maximum adsorption capacity value at 14.286 mg kg-1in the sample point IV (unpolluted soil). The optimum desorption of chromium occurred at pH 3. Toxicity test showed that Cr ions had toxic effect to Brassica junceaand Helianthus annuus L.

Summary

Introduction

Tannery industry is an industry that treats a variety of raw leather, semi-finished leathers (pellicle and wet-blue leathers) to become finished leather. The leather tanning industry is categorized as one of the high polluting industries because of tanning activities that have an adverse effect on the environment. This is due to industrial wastes which if not managed properly. The government has implemented regulations and provisions regarding industrial obligations in processing waste, including those contained in Law of the Republic of Indonesia Number 32 year 2009 concerning Protection and Management of Environment; Indonesia Government Regulation Number 101 year 2014 regarding Hazardous and Toxic Waste Management. Leather tanning waste water include hazardous waste because they contain heavy metals such as chromium. Significant chromium concentrations are released into the environment through leather tanning industry (Sneddon, 2012)
