Pollen levels have declined slightly this week after spending all of last week at "very high" levels, according to local pollen counts and forecasts.
But they are still elevated. Tree pollen was measured at 183 grains per cubic meter of air Tuesday, according to Drs. Golden and Matz LLC, an allergist practice in Owings Mills. Grass pollen was at 51 grains per cubic meter, considered very high.
Pollen levels skyrocketed about the beginning of the month according to records kept by Drs. Golden and Matz and the Weather Channel. Last week, they were more than 10 times the levels reported Tuesday, at 2,500 to 3,400 grains per cubic meter.
Tree pollen, including hickory, sycamore, oak, ash, maple, elm and poplar, is at high levels across the Northeast and around the Great Lakes, according to the Weather Channel.
The cable network predicts grass pollen will subside in the coming days, while tree pollen could spike again.
