53 extractive question-and-answer pairs built from Microsoft Word - Draft Report-NMPA-Half Yearly Compliance (Sep 25 - Feb 26), published by newmangaloreport.gov.in. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. 9 of the 53 pairs (17.0%) are explanatory questions and 44 restate a figure. 100.00% of rows pass the corpus quality gate.

| What studies were conducted to monitor environmental conditions in the field? | carried out for ambient air, noise level | Being concerned towards environmental protection NMPA has prepared an extensive environmental management plan for port operations. The field environmental monitoring studies were carried out for ambient air, noise level. Stack emission, marine and drinking water quality, sludge and waste water quality, and half yearly compiled data arc presented here. | 179 | definition | 1.000 | The field environmental monitoring studies were carried out for ambient air, noise level. | 5 | page=5,block=9 | 0.850 | valid |
| What is used to determine heavy metals with ICP-OES? | used for determination of heave metals by using ICP-OES | Appropriate weight of sample was subjected for digestion with aqua-regia. Filtrate was used for determination of heave metals by using ICP-OES. Benzene (C6H6) Air was drawn through a charcoal tube at the adjusted flow rate of 0.05 LPM for a period 4 hours to get representative volume of sample. | 87 | definition | 1.000 | Filtrate was used for determination of heave metals by using ICP-OES. | 7 | page=7,block=0 | 0.850 | valid |
| What data is used to determine ambient SO2 concentrations? | the amount or S02 collected and the volume of air sampled | The sampling of ambient air for evaluating the gaseous pollutants were performed with a multi gas Sampler, using the vacuum created by the FDS Sampler for drawing the air samples through the impingers. ForSO2, air was drawn at a measured and controlled rate or 0. LPM & passed through a solution of potassium tetrachloromercurate (TCM). After sampling, the absorbing reagent was treated with dilute solutions of sulfamic acid, formaldehyde and para--rosaniline hydrochloride. The absorbance of the intensely coloured para-rosaniline methyl sulphonic acid was measured at the wavelength of 560nm using spectrophotometer and the amount of S02 in the sample was computed. The ambient S02 concentrations were computed from the amount or S02 collected and the volume of air sampled. Oxides of Nitrogen (NO2) Air was drawn at a measured and controlled rate of about 0. | 719 | summary | 0.970 | The ambient S02 concentrations were computed from the amount or S02 collected and the volume of air sampled. | 6 | page=6,block=12 | 0.700 | valid |
| What is used to calculate ambient NO2 concentrations? | the total nitrite ion present in the impingers | LPM through an orifice-tipped impinger containing solutions of sodium hydroxide and sodium arsenite. After completion of the sampling, an aliquot of the used absorbing solution was treated with solutions of H2O2. Sulphanilamide and NEDA. The nitrite ion present in the impinger was calculated from the absorbance of the resulting solution measured at 540 nm using spectrophotometer. The ambient NO2 concentrations were computed from the total nitrite ion present in the impingers. Overall efficiency of the impinger and the procedure, and the volume of air sampled. Carbon Monoxide (CO) Rubber Bladder and Aspirators have been used to collect the 8 hourly samples for Carbon Monoxide. The CO levels were analysed through NDIR. Ozone (O3) Air is drawn through a midget impinger containing potassium iodide in a neutral buffer in 2 LPM for a period of 60 minutes. | 433 | summary | 0.970 | The ambient NO2 concentrations were computed from the total nitrite ion present in the impingers. | 6 | page=6,block=12 | 0.700 | valid |
| How is the concentration of PM10 determined? | from the average air flow rate, sampling period and the mass of particulate matter collected over the filter surface | Particulate Matter (PM10) The sampling of ambient air for evaluating PM10 levels were performed with a RDS Sampler fitted with a cyclone separator. Air exiting the separator is drawn at a measured rate through pre-weighed glass fiber filter sheets of 20cm x 25cm sizes. The concentration of PM10 were computed from the average air flow rate, sampling period and the mass of particulate matter collected over the filter surface. | 310 | summary | 0.930 | The concentration of PM10 were computed from the average air flow rate, sampling period and the mass of particulate matter collected over the filter surface. | 6 | page=6,block=10 | 0.700 | valid |
