Sentence examples for pollutant i from inspiring English sources

The PI was determined as follows: {text{PI}} = frac{{C_{i} }}{{S_{i} }}, (1 where ({text{PI }}) is the pollution index of the pollutant i at the mine dump site; (C_{i}) is the measured concentration value of the heavy element i; S i is the concentration value of the respective metal in the uncontaminated virgin forest soil.

In Fig. 1, C sij is the air concentration of the pollutant i at the surface of the material j.

According to the formula published by the MEP [22], the AQI is expressed as follows: mathrm{AQI}=max left({mathrm{IAQI}}_1,{mathrm{IAQI}}_2,dots, {mathrm{IAQI}}_nright) (2 where IAQIi is the individual air quality index value for the i-th air pollutant, i = 1, 2, …, n and n denote the number of air pollutants.

At the material/air interface, VOC mass transfer can be expressed as: Q_{ij} = h_{ij} frac{{A_{j} }}{V}(C_{sij} - C_{i} ) (3)where h ij is the convective mass transfer coefficient of pollutant i through the boundary layer over the material j (determined from empirical relationships [8] ), A j the surface area of the material j and V the volume of the room.

For simplicity, we only considered one pollutant, i.e. NOx.

This definition of critical soil acid load applies to exposure of the soil to a single, long-term pollutant (i.e., acidic deposition).

Although separating individuals from pollution sources is likely to have health benefits, not all pollutants (i.e., ozone) decrease with increasing distance from roadways (Beckerman et al. 2008).

It is worth noting that these two cohort studies [ 35, 50] only used annual average PM2.5 concentrations as the air pollution exposure index, not simultaneously considered the effects of other air pollutants (i.e., SO2, NO, NO2, O3, and PM10) on the observed association; and the measure of effect was mortality rather than incidence.

Two organic compounds were chosen as model pollutants, i.e. ethanol and polyalkylated benzenes.

Differently, typical primary pollutants (i.e. from combustion and road traffic) increased during slow wind regimes.

These alternatives are related to the overall goal through two water pollutants, i.e., NH4+-N and COD.
