“…These topics have formed the basis of a number of recent (past five years) books [1][2][3], which could be taken as a sign that there is sustained interest in the topics. Although published in 2005, Professor Andrew Meharg's Venomous Earth [4] an account of the interaction of the various life forms on our planet with a variety of arsenic-containing chemicals, written for a general readership, is a good starting point.…”

A large number of publications describe the determination of arsenic in “environmental” samples in the broadest sense, a substantial subset of which focus on plant-based foodstuffs. There is a considerable interest in the inorganic arsenic content of food, especially rice, as there is recent evidence that concentrations may be high enough to exceed acceptable risk thresholds. The methodology for the determination of arsenic in rice is critically evaluated and results (a) for a rice flour reference material (National Institute of Standards SRM 1568a, certified only for total arsenic) and (b) a recent proficiency test (run by the European Commission's Joint Research Centre Institute for Reference Materials and Measurement) are examined. Difficulties with this particular analysis may lie in the sample preparation stages, over which there is still disagreement with regard to species stability, though a simple, hot-water extraction may be sufficient. High performance liquid chromatography separations with plasma-source mass spectrometry detection are popular; however, chromatographic separations are often not adequately described, the enhancement effect of carbon-containing species is often overlooked, and the fate of chlorine-containing species, responsible for an isobaric overlap interference, often obscure. Compound-dependent responses, for which there is a plenty of evidence, are almost never acknowledged or discussed.

As a consequence, millions of people are in problem for long-time because of arsenic poisoning from the water they drink [1].For longer period obsessive of arsenic that can effect skin and lung cancers, as well as cancers of the urinary tract, kidney, and liver; Reproductive system and growth in child health can be effected.

Water, the inevitable need of any individual, must be monitored. Detection of the arsenic chemical present in water leads to contagious diseases. The legacy makes people difficult to survive. The consequences are cancer, other diseases. Employing photonic crystal waveguide with the rally round of mach Zehnder interferometer, it is feasible to correctly compute arsenic compound level in water. MZI sensor has many compensation, diminutive, least use of instrumentation, and ready to be used with CMOS technology. Follows in the paper, arsenic compound level of wavelength range of 1530-1565 nm is analyzed and detected. Experiential program from the band arrangement that for minute change in refractive index is accounted, subsequently logical shift in the frequency and amplitude will be evident enlarging mach Zehnder interferometer will behave as a sensor. Thus projected alternate included optical Mach Zehnder Interferometer (MZI), composed of graded index channel waveguide that can be frequently used as chemical and biological sensor in this manuscript. This dissertation describes how the MZI operates two arms predominantly to conquer the industrial challenges. Manuscript represents test data, graph and results that exemplify the performance of whole system.
