RESEARCH PROFILE

 

Arsenic poisoning, related health effects and its detection

Arsenic (As) is a metalloid widely distributed in the earth’s crust and ranked 20th most abundant element in the earth. This element is included in the U.S. Environmental Protection Agency’s list of priority pollutants with an atomic number of 33 and an atomic mass of 74.91 and can exist in four valency states: -3, 0, +3 and +5. This toxic element has deleterious effects on human health through contamination of the food chain or drinking waters. The health effects due to chronic exposure to inorganic arsenic in the drinking water may manifest primary dermatological features such as melanosis (pigmentation) and keratosis (rough, dry, papular skin lesions), both may be spotted or diffuse along with gastrointestinal, liver, respiratory, neurological, hematological, cardiovascular, obstetric, diabetic effects and other factors. It is thought that chronic arsenic exposure may cause multisystemic disorder. Ingestion of inorganic arsenic has been shown to cause even skin cancer, bladder, and lung cancer thus inorganic arsenic is classified by the International Agency for Research on Cancer as Class A human carcinogen.

Over the past three decades, occurrence of high concentrations of arsenic in drinking-water has been recognized as a major public-health concern in several parts of the world. Hence time to time monitoring of hand tubewells, food crops, soil, plants etc. for the detection of arsenic using low cost portable devices involving simple technique, setup as well as robustness of the instrument is the need of the hour and the group is involved in such work for almost a decade.

 

CURRENT PROJECTS

 

Flow Injection Electrochemical Arsine generation and gas phase chemiluminescence generation (FI-EAG-GPCL)


  1. Setting up the FI-EAG-GPCL for the measurement of total arsenic
  2. Optimizing the FI-EAG-GPCL w.r.t As(V) sensitivity
  3. Optimization the As(V) sensitivity using porous membrane based GLS
  4. Speciating As(III) & As(V) w.r.t the difference in operating current
  5. Validating the setup with real sample analysis

See Figure 1a for system schematics and Figure 1b photograph of the Electrochemical Reactor and Figure 2; system response.

 

Study on the response of MCF-7 (Human breast cancer cell) grown in arsenic rich media


  1. MCF-7 cells were treated with As(V) from lower to higher concentrations
  2. MCF-7 cells were treated with As(III) & As(V) to check the acute toxicity difference
  3. Understanding the tolerance of MCF-7 cells in successive generations
  4. Understanding the mechanism of As(V) intake with changing the phosphate concentration

 

Study on the efficiency of various designs Gas Liquid separator


Gas Liquid separator plays a vital role in analyte transport to the detector. It increases the signal intensity if the analyte is completely transported also a critical factor in signal reproducibility. Different designs of GLS are made by varying the size and type of the material used to check the efficiency as shown in the Figure 3.

 

Online microwave digestion – ICPMS detection for measuring metal ions in air samples


An online setup is been designed where the ambient air is drawn with the help of a cyclone and the intended metal ions which is to be detected is passed through a microwave digester and a real time was detected via ICP-MS.

 

PROJECTS COMPLETED

 

Liquid Chromatographic coupled with GPCL setup for speciating As (LC-GPCL)


A post column gas phase chemiluminescence system (LC-GPCL system) for separation and detection of inorganic & organic As species [As(III), As(V), DMA & MMA] in environmental samples was developed. This set-up was employed to study the presence of various As species in soil and dust samples. Inorganic As(V) was the only species found in these samples. The LOD for the In sulfuric acid-based extracts were 2.6, 1.3, 6.7, and 6.4µg/L for As(III), As(V), dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA), respectively. (For details about this study, please see …)

 

 

Gas phase chemiluminescence based analyzer with manual dispenser (M-GPCL analyzer)


An inexpensive sensitive gas-phase chemiluminescence (GPCL) based analyzer for arsenic was developed which utilizes manual fluid dispensing operations to reduce size, weight and cost. The analyzer has a LOD of 1.0 mg/L total inorganic As (peak height based, 3 mL sample). The system performance was validated after measuring arsenic in tap water samples from Texas and New Mexico and compared with results obtained by inductively coupled plasma-mass spectrometry (ICP-MS), and a high correlation was observed. This affordable approach is not only applicable to water; it is applicable to soil extracts and likely many other matrices at a cost <1% of that of ICP-MS and still provide an LOD comparable with that from a large, expensive instrument. Very little operator skill is required for this analyzer thus providing cheaper solutions for detecting arsenic in millions of hand tubewells heavily laced with arsenic in countries like India and Bangladesh where capital investment into major instrumentation is harder to come by compared to relatively inexpensive labor. (For details please see…)

 

Hydride generation – ICP MS method for total As measurement (HG- ICP MS)


An automated hydride generation (AHG) interface to inductive coupled plasma mass spectroscopy (ICPMS) was developed for measuring total arsenic in environmental samples. This technique provides statistically indistinguishable response slopes (within about 3%) for hydride generation-ICPMS (HG-ICPMS) analysis of all major As species, inorganic As(III), dimethylarsinic acid (DMA), momomethylarsonic acid (MMA), and inorganic As(V); this has not previously been achieved. Previously, sample pretreatment to convert all forms of As into As(V) has been a prerequisite for measuring total arsenic in complex matrices. Under our operating conditions, arsenobetaine (AsB), until now regarded to be inert, also generates a hydride (albeit the response is only ~7% of others). The limit of detection (LOD) based on three times the standard deviation of the blank with this technique for AsB, DMA, As(III), MMA, and As(V) is 90, 66, 63, 63, and 63 pg

As, respectively. This AHG-ICPMS technique was compared with a flow injection-UV photolysis-HG-ICPMS (FIUV-ICPMS) and liquid chromatography-UV-HG-ICPMS analysis of arsenic content in National Institute of Standards & Technology (NIST) standard rice flour (standard reference material: SRM 1568a) and rice samples collected from West Bengal, India. Both oxidative acid digestion and methanol: Water (1:1) extractions were used. The analytical results for total As in the SRM 1568a digest were 99.2 ± 0.6 and 100.2 ± 0.8% of the certified value (290 ±3 µg As/kg) by the AHG-ICPMS and the FI-UVHG-ICPMS techniques, respectively. For rice extracts and the digests, the two techniques provided results that were correlated with linear r2 values of 0.9988 and 0.9987 with intercepts statistically indistinguishable from zero. (For details please see…)

 

Liquid Chromatography coupled with Hydride generation-ICPMS for As speciation (LC-UV-HG-ICPMS)

 

In LC-UV-HG-ICPMS; the chromatographic columns (AG-23 HC guard, and AS-23 HC separator column) were used with a low-end isocratic pump (DX-100). To accomplish step gradient elution, a four-input selector solenoid was implemented under a programmable DVSP-4 digital valve sequencer. The step gradient elution program started with DIW (eluent A) and switched to 4 mM Na2CO3 + 0.8 mM NaHCO3 (eluent B) at 2 min which was switched to 60 mM Na2CO3 + 30 mM NaOH (eluent C) at 8 min, all at 1 mL/min. At 15 min, the eluent was switched back to A; a new injection cycle begun after a 6 min re-equilibration period. The LOD is estimated for AsB, DMA, As(III), MMA, and As(V) to be 1.92, 1.45, 1.77, 1.92, and 3.21 pg As, respectively. This set-up was employed to detect different species present in rice samples collected from As effected areas. Chromatographic analysis indicated that As in these rice samples were 75-90% inorganic. (For details please see…)
