survey and heavier rain later in the morning. The survey was
preceded by moderate rainfall 24 hours prior sampling (13.5 mm) at Brooklands Zoo rain gauge. There was
a light mist/intermittent drizzle during sampling. Over the last seven days prior sampling 66 mm of rain was
measured at Brooklands Zoo rain gauge. Samples collected were also assessed for odour.
Out of the 11 samples collected, one had a distinctive odour, described as earthy/woody, coming from
STW001157, which suggests the

daily average results fell
into the Ministry's 'excellent' or 'good' categories and 41% of the results met the 'acceptable'
category. Six daily results from the total 138 of days monitored fell into the ‘alert’ category. It
is noted that all of those six results happened during moderate to heavy rainfall events, and
in the majority of cases, during fresh onshore winds. These findings confirm those of the
previous inhalable particulate surveys that found sea salt spray to be a major PM10 source.
