“…MEM is a method whose accuracy and precision have been demonstrated by many researchers (Kokot, King, Keller, & Massart, 1992;Paudyn & Smith, 1992;Tanner & Leong, 1997) and is used to measure the leaching of "acid-soluble elements" from sediments, sludges, soils, and oils (EPA, 1998). 0.5 g of each sample were placed in vessels to which 10 ml of nitric acid (Mitsubishi Chemical Corporation, high purity EL grade nitric acid) was added and were digested in a microwave digestion system (PerkinElmer Japan, MDS-2000; operating conditions: temperature raised to 175°C in approx.…”

Heavy metal concentrations of the acidsoluble fraction in sediment core samples from Nagaike, a reservoir in Osaka City, Japan, were measured by ICP-MS following the microwave extraction method. Spiked peaks for several metals in the sediment core samples were observed around 1960. The results of correlation coefficient study and cluster analysis of heavy metal concentrations in the sediment core samples showed that some metals, such as Cr, Cd, Ni and Cu, in the period of the spiked peak were derived from the different emission sources from other periods. These metals are often used for metal plating, and it was concluded that the spiked peaks were caused by illegal effluent from the metal plating industry. The load amounts of heavy metals by illegal dumping were calculated and the magnitude of the pollution was estimated.

EVALUATION OF THE USE OF CHEMOMETRIC METHODS IN SOIL ANALYSIS. One of the major interests in soil analysis is the evaluation of its chemical, physical and biological parameters, which are indicators of soil quality (the most important is the organic matter).Besides there is a great interest in the study of humic substances and on the assessment of pollutants, such as pesticides and heavy metals, in soils. Chemometrics is a powerful tool to deal with these problems and can help soil researchers to extract much more information from their data. In spite of this, the presence of these kinds of strategies in the literature has obtained projection only recently. The utilization of chemometric methods in soil analysis is evaluated in this article. The applications will be divided in four parts (with emphasis in the first two): (i) descriptive and exploratory methods based on Principal Component Analysis (PCA); (ii) multivariate calibration methods (MLR, PCR and PLS); (iii) methods such as Evolving Factor Analysis and SIMPLISMA; and (iv) artificial intelligence methods, such as Artificial Neural Networks.Keywords: chemometrics; soil analysis; principal component analysis. DIVULGAÇÃO INTRODUÇÃOCom a crescente sofisticação das técnicas instrumentais de análise química, impulsionada pela invasão de microprocessadores e microcomputadores no laboratório, técnicas de tratamentos de dados mais complexas do ponto de vista matemáti-co e estatístico tornaram-se necessárias 1 . A análise de dados é uma parte essencial em todo experimento, sendo univariada quando somente uma variável é medida sistematicamente para várias amostras. Há muito tempo a estatística univariada vem sendo aplicada a problemas químicos, mas a sua utilização tornou-se limitada. Nas últimas décadas, a aná-lise multivariada foi introduzida no tratamento de dados quími-cos, ganhando rapidamente popularidade e dando origem a uma nova disciplina, batizada de Quimiometria. O modelo estatístico dos métodos multivariados considera a correlação entre muitas variáveis analisadas simultaneamente, permitindo a extração de uma quantidade muito maior de informação.Neste artigo será avaliada a utilização de métodos quimiométricos em análise de solos. O solo é uma estrutura complexa formada pela influência de fatores geológicos, topográficos, climáticos, temporais e antropogênicos; sendo a parte mais importante da geosfera e de onde provêm a maior parte dos nossos alimentos. Além disso, ele funciona como uma espécie de filtro ambiental para a purificação da água e do ar 2 . O interesse maior na análise de solos está na avaliação de seus parâmetros químicos (concentração de metais e nutrientes, pH, etc.), físicos (compactação, umidade, etc.) e biológicos (microrganismos, etc.), os quais são um indicador de sua qualidade. Dentre os constituintes do solo, o mais estudado é a matéria orgânica (MO). Esta controla muitas de suas propriedades e é um fator central na manutenção de sistemas agrícolas sustentá-veis. Práticas que favoreçam a conservação da MO melhoram as propriedades ...
