Lichens were recorded on Quercus petraea trunks and twigs near ammonia recording stations in ‘continental’ Norfolk, and ‘oceanic’ Devon in order to test indicator values developed for epiphytic lichens in areas of high atmospheric ammonia in the Netherlands. Lichens on trunks in Norfolk showed a similar correlation of nitrophyte indices with ammonia concentration and bark pH as those in Holland, whereas in Devon there was no correlation with nitrophyte indices on trunks and a negative correlation with acidophyte indices. Results on twigs in both sites suggest that lichens on twigs respond more rapidly to recent changes in ammonia concentrations while trunks may maintain relict lichen communities due to either a legacy of previous acidification or ecological continuity. The results suggest that loss of acidophytes is taking place prior to the establishment of nitrophytes indicating the importance of establishing levels of ammonia at which sensitive communities are at risk.

Atmospheric ammonia is a significant pollutant throughout the year, necessitating standardized measurement and identification of emission factors. We performed a quantized evaluation of ammonia concentrations at various locations in and around Seoul, South Korea. The established testing methods of the Radiello Passive Sampler were used for ammonia sampling, and the method was validated using annular denuder sampling. Urban and suburban areas were studied to gain a deeper understanding of the factors responsible for ammonia pollution. This study aimed to establish the fluctuations in concentration over one year, by analyzing the seasonal and regional variation in ammonia concentration. Livestock and agricultural areas recorded the highest concentration of ammonia among all sites, with the highest concentration recorded in autumn. However, at most of the other studied sites, the highest and lowest ammonia concentrations were recorded during summer and winter, respectively. This study attempted to establish a correlation between ammonia concentration and temperature, as well as ammonia concentration and altitude.

The concentration of ammonia was measured in the air space of 180 houses of 30 pig enterprises in Greece during an 8-month period by using tubes that chemically bind atmospheric ammonia. The mean overall ammonia concentration was 24.6 ppm (10-52 ppm). The mean ammonia concentration according to the age group of the animals was 26.4 ppm in finishing pig houses, 26.2 ppm in growers' pig houses, 22.6 ppm in flat-deck units and 19.8 ppm in farrowing houses (p<0.05). With regard to the type of the floor, the mean ammonia concentration was 28.0 ppm in concrete-floored houses and 21.4 ppm in slatted-floored ones (p<0.05), and as regards the season of the year, higher concentrations were measured at winter time (27.7 ppm) compared to those seen during spring (24.5 ppm) and summer time (21.1 ppm) (p<0.05). The findings are discussed in relation to the adverse effects that ammonia may have for pig's health and production.
